\begin_layout Section
What is \SpecialChar LyX
?
\end_layout

\begin_layout Standard
\SpecialChar LyX
 is a document preparation system.
 It is a tool for producing beautiful manu\SpecialChar softhyphen
scripts, publishable books, business
 letters and proposals, and even poetry.
 It is unlike most other 
\begin_inset Quotes eld
\end_inset

word processors
\begin_inset Quotes erd
\end_inset

 in the sense that it uses the paradigm of a markup language as its core
 editing style.
 That means that when you type a section header, you mark it as a 
\begin_inset Quotes eld
\end_inset

Section
\begin_inset Quotes erd
\end_inset

, not as 
\begin_inset Quotes eld
\end_inset

Bold, 17
\begin_inset space \thinspace{}
\end_inset

pt type, left justified, 5
\begin_inset space \thinspace{}
\end_inset

mm space below
\begin_inset Quotes erd
\end_inset

.
 \SpecialChar LyX
 takes care of the typesetting for you; so you deal only with concepts,
 not with mechanics.
\end_layout

\begin_layout Standard
This philosophy is explained in greater detail in the 
\emph on
Introduction
\emph default
 manual.
 If you haven't read it yet, you need to.
 Yes, we mean now.
\end_layout

\begin_layout Standard
The 
\emph on
Introduction
\emph default
 manual describes several things in addition to \SpecialChar LyX
's philosophy: most importantly,
 the format of all of the manuals.
 If you don't read it, you will have a bear of a time navigating this manual.
 You might also be better served looking in one of the other manuals instead
 of this one.
 The 
\emph on
Introduction
\emph default
 manual describes that, too.
\end_layout

\begin_layout Section
How \SpecialChar LyX
 Looks
\end_layout

\begin_layout Standard
Like most applications, \SpecialChar LyX
 has the familiar menu bar across the top of its
 window.
 Below it is a toolbar with a pulldown box and various buttons.
 There is, of course, a vertical scrollbar and a main work area for editing
 documents.
\end_layout

\begin_layout Standard
Note that there is no horizontal scrollbar.
 This is not a bug or an oversight, but intentional.
 When you read a book, you expect the end of a line to wrap around to the
 next line.
 Text overflows onto new pages in a vertical fashion, hence the need for
 only a vertical scrollbar.
 There are three cases where you might want a horizontal scrollbar.
 The first case is large images.
 To avoid them being displayed larger than your screen, left click on the
 image and use the option 
\family sans
Scale on Screen
\family default
 in the tab 
\family sans
\SpecialChar LaTeX
 and \SpecialChar LyX
 options
\family default
.
 The second and third cases are tables and equations which are wider than
 the \SpecialChar LyX
 window.
 You can use the arrow keys to scroll horizontally through the table, but
 this doesn't work for equations yet.
\end_layout

\begin_layout Standard
For a brief description of all \SpecialChar LyX
 menus and toolbar buttons, have a look at

HELP
\end_layout

\begin_layout Standard
The help system consists of the \SpecialChar LyX
 manuals.
 You can read all of the manuals from inside \SpecialChar LyX
.
 Just select the manual you want to read from the 
\family sans
Help
\family default
 menu.

\begin_inset Index idx

\begin_layout Plain Layout
Preferences
\end_layout

\end_inset

 \SpecialChar LyX
 is able to inspect your system to see what programs, \SpecialChar LaTeX
 document classes
 and \SpecialChar LaTeX
 packages are available.
 It uses this knowledge to give reasonable defaults for the preferences
 settings.
 Although this configuration has already been done when \SpecialChar LyX
 was installed on
 your system, you might have some items that you installed locally, e.

\begin_layout Standard
You can edit documents in \SpecialChar LyX
 without having \SpecialChar LaTeX
 installed, but you will not be
 able to create PDFs or print your documents unless you do have it installed.
 However, some \SpecialChar LyX
 documents use DocBook as the “backend” that can produce
 PDFs and the like, and every \SpecialChar LyX
 document can always be output as plain text
 or as XHTML.
\end_layout

\begin_layout Standard
Some document classes may depend upon specific \SpecialChar LaTeX
 or DocBook classes or packages.
 Such document classes can be used even if you do not have the required
 files installed, but you will not be able to produce certain kinds of output.
\end_layout

 into individual cells.

In the pull-down box at the top of the outline window, you can choose between
 several different lists, including other TOC-like objects, such as lists
 of tables and figures, but also lists of footnotes, or labels and cross-referen
ces (see section
\begin_inset space ~
\end_inset


\begin_inset CommandInset ref

\end_inset

), or notes, or citations (see section
\begin_inset space ~
\end_inset


\begin_inset CommandInset ref

\end_inset

).
 Clicking on any of these will take you to the corresponding object in your
 document.
\end_layout

\begin_layout Standard
Right-clicking on elements in the Outline opens in many cases a context
 menu that will allow for direct modification of those elements.
 For example, with citations, the context menu allows you to open the citation
 dialog and to modify the citation.
\end_layout

\begin_layout Standard
The 
\family sans
Filter
\family default
 field at the top allows you to restrict which entries appear in the outline.
 For example, if you are displaying the list of 
\emph on
Labels and References
\emph default
 and wish to see only references to subsections, you can enter the text
 
\begin_inset Quotes eld
\end_inset

sub
\begin_inset Quotes erd
\end_inset

 in the filter, and only entries containing that text will be displayed.
\end_layout

\begin_layout Standard
At the bottom of the outline are several buttons and the like that allow
 you further to control the display.
 The 
\family sans
Sort
\family default
 option sorts the current list alphabetically.
 Otherwise, the elements appear in the order in which they occur in the
 document.
 The 
\family sans
Keep
\family default
 option keeps it in the current view state.
 Keeping means that when you have, for example, the subsections of sections
\begin_inset space ~
\end_inset

2 and 4 displayed and click on section
\begin_inset space ~
\end_inset

3, the subsections of sections
\begin_inset space ~
\end_inset

2 and 4 will still be displayed.
 Without the 
\family sans
Keep
\family default
 option they will be hidden to highlight the clicked section
\begin_inset space ~
\end_inset

3.
 Finally, the slider at the left can be used to open the Outline to a given
 
\begin_inset Quotes eld
\end_inset

depth
\begin_inset Quotes erd
\end_inset

.
 It is best just to experiment with it to see how it works.
\end_layout

\begin_layout Standard
The 
\begin_inset Info
type  "icon"
arg   "reload"
\end_inset

 button refreshes the TOC (though this should not usually be necessary).
 Next to it are buttons that allow you to change the position of sections
 in your document.
 The 
\begin_inset Info
type  "icon"
arg   "outline-down"
\end_inset

 and 
\begin_inset Info
type  "icon"
arg   "outline-up"
\end_inset

 buttons move sections up and down in the document.
 So, for example, you can move section
\begin_inset space ~
\end_inset

2.5 before section
\begin_inset space ~
\end_inset

2.4 or after section
\begin_inset space ~
\end_inset

2.6.
 \SpecialChar LyX
 will then automatically renumber the sections to the new order.
 With the buttons 
\begin_inset Info
type  "icon"
arg   "outline-out"
\end_inset

 and 
\begin_inset Info
type  "icon"
arg   "outline-in"
\end_inset

 (or the corresponding key bindings 
\family sans
Tab
\family default
 and 
\family sans
Shift-Tab
\family default
) you can change the level of sections.
 So you can for example make section
\begin_inset space ~

2.5 chapter
\begin_inset space ~
\end_inset

3 or subsection
\begin_inset space ~
\end_inset

2.4.1.

Introduction
\end_layout

\begin_layout Standard
Before you do anything else, before you ever start writing a document, you
 need to decide what type of document you want to edit.
 Different types of documents use different types of spacing, headings,
 numbering schemes, and so on.
 Additionally, different documents use different paragraph environments,
 and format the title of your document differently.
\end_layout

\begin_layout Standard
A 
\emph on
document class
\emph default
 describes a group of properties common to a particular set of documents.
 By setting the document class, you automatically select these properties,
 making it easier to create the type of document you want.
 If you don't choose a document class, \SpecialChar LyX

Overview
\end_layout

\begin_layout Standard
There are four standard document classes in \SpecialChar LyX
.
 They are:
\end_layout

\begin_layout Description
Article for basic articles
\end_layout

\begin_layout Description
Report for basic reports
\end_layout

\begin_layout Description
Book for writing a book
\end_layout

\begin_layout Description
Letter for US-style letters
\end_layout

\begin_layout Standard
There are also some non-standard classes, which \SpecialChar LyX
 only uses if you have installed
 the corresponding \SpecialChar LaTeX
 class files, though most \SpecialChar LaTeX
 distributions will include
 many of these.
 Here are some of the classes.
 The full list with detailed explanations can be found in chapter 
\emph on
Special Document Classes
\emph default
 in the 
\emph on
Additional Features

 manual:

\begin_layout Description
ACS For submissions to the journals published by the American Chemistry

\begin_layout Description
AGU For submissions to the journals published by the American Geophysical
 Union
\end_layout

\begin_layout Description
AMS Layouts for articles and books in the style and format used by the American
 Mathematical Society (AMS).
 There are three article layouts available.
 The standard one uses a typical numbering scheme for theorems etc., that
 prepends the section number to the number of the result.
 All result-type statements (propositions, corollaries, and so on) are sequenced
 together, but definitions, examples, and the like have their own sequence.
 The 
\begin_inset Quotes eld
\end_inset

sequential numbering
\begin_inset Quotes erd
\end_inset

 scheme does not place the section number with each result, but numbers
 them throughout the article in a single sequence.
 Each type of result gets its own sequence.
 There is also a layout that dispenses with numbering of statements altogether.

 Here, we will settle for a list of some of the common properties of all

.
 If you open a document that uses such a class, you will receive a warning
 saying that there are files that are required to produce output that are
 not installed.
 So it may seem that something is wrong.
\end_layout

\begin_layout Standard
Nothing is wrong.
 \SpecialChar LyX
 includes many more document classes than you will ever need to use, and
 some of them, like 
\family sans
IOP
\family default
, are highly specialized.
 \SpecialChar LyX
 tries to support as many different types of documents as possible, and
 it includes almost one hundred different layout files, with a growing number.
 No \SpecialChar LaTeX
 distribution will install by default all files that might be needed
 by some document class.
 There are just too many of them.
 That is why some of the document classes are unavailable.
\end_layout

\begin_layout Standard
If there is a document class you would like to use that is marked as 
\begin_inset Quotes eld
\end_inset

Unavailable
\begin_inset Quotes erd
\end_inset

, you just need to install the appropriate package files.
 The easiest way to find out which files you need to install is to use that
 document class for a new file.
 \SpecialChar LyX
 will display a dialog that will list the missing files.
 See section 
\emph on
Installing new \SpecialChar LaTeX
 files
\emph default
 in of the 
\emph on
Customization

 manual for information on how to install them.

\end_layout

\begin_layout Standard
Although \SpecialChar LyX
 provides support for many different sorts of documents, it does
 not include support for every document class people might want to use.
 For example, many universities provide \SpecialChar LaTeX
 class files to be used for dissertation
s submitted to those universities.
 The \SpecialChar LyX
 team cannot write layout files to support every one of these.
 There are too many.
 Fortunately, users can write their own layout files, and many users have
 done so.

\end_layout

\begin_layout Standard
Modules load additional features that are not by default available in the
 chosen document class.
 For example you might want to write Braille (embossed printing) in a document.
 This is not available in any document class, so you have to load the correspond
ing module in the 
\family sans

 Highlighting a module in the dialog will bring up a description of what
 it does.
\end_layout

\begin_layout Standard
Some modules require \SpecialChar LaTeX
 packages or file format converters that are not always
 installed by default.
 \SpecialChar LyX
 will warn you if you do not have a required package or converter, and
 it will tell you what exactly you are missing.
 You can still use the module while editing your file, but you will not
 be able to export to PDF or print your document, since \SpecialChar LyX
 will not be able
 to compile the \SpecialChar LaTeX
 file without the missing prerequisites.
 If you want to be able to produce this kind of output, then you need to
 install the missing prerequisites and then reconfigure \SpecialChar LyX

\begin_layout Standard
Modules are to \SpecialChar LyX
 much as packages are to \SpecialChar LaTeX
: They are intended to be used in
 a variety of different documents.
 If you often find yourself needing the same sort of thing in different
 documents, you should consider writing a module for this purpose.
 Sometimes, however, a particular document has very special needs, but you
 need a specific inset or character style only that one time.
 You want something that is like a document's own \SpecialChar LaTeX
 preamble.

Important Note
\end_layout

\begin_layout Standard
If you change a document class, \SpecialChar LyX
 has to convert 
\emph on
everything
\emph default
 into the new class.
 That includes the paragraph environments.
 Some paragraph environments are standard, in so far as all of the document
 classes have them; but some classes have special paragraph environments.
 If this is the case, and you change the document class, \SpecialChar LyX
 will mark the
 paragraphs whose styles it no longer understands as 
\begin_inset Quotes eld
\end_inset

unknown
\begin_inset Quotes erd
\end_inset

.
 The name of the style is retained, in case you should want to go back to
 the old class.
 But these paragraphs will be output with no special formatting, so you
 will either need to create a new style yourself or else convert these paragraph
s manually to a style present in your new document class.

\begin_layout Standard
Before describing all of the various paragraph environments, we'd like to
 say a word or two about paragraph indentation.
\end_layout

\begin_layout Standard
Everyone seems to have their own convention for separating paragraphs.
 Most Americans indent the first line of a paragraph.
 Others don't indent but put extra space between the paragraphs.
 If you choose indentation for paragraphs the 
\emph on
first
\emph default
 paragraph of a section, or after a figure, an equation, a table, a list,
 etc., is 
\emph on
not
\emph default
 indented.
 Only a paragraph following another paragraph gets indented.
 Note that the indentation behavior is different when you use another document
 language than English.
 \SpecialChar LaTeX
 takes care that the indentation follows the rules of the language used.
\end_layout

\begin_layout Standard
The space between paragraphs, like the line spacing, the space between headings
 and text — in fact, all the spacing for just about everything —is pre-coded
 into \SpecialChar LyX
.
 As we said, you don't worry about how much space to add between what.
 \SpecialChar LyX
 takes care of that.
 In fact, these pre-coded vertical spacings aren't a single number but a
 range.
 That way, \SpecialChar LyX
 can squish or stretch the space between lines to make sure figures
 fit on a page with text, so that sections don't start at the bottom of
 a page, and so on.
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
\SpecialChar LaTeX
 does this when \SpecialChar LyX
 goes to produce a printable file.
\end_layout

\end_inset

 However, pre-coded doesn't mean you can't change them.
 \SpecialChar LyX
 gives you the ability globally to change 
\emph on
all
\emph default
 these pre-coded spacings.
 We will explain more later.

 If you don't know \SpecialChar LaTeX

 alien to you, we urge you to read the 
\emph on
Tutorial
\emph default
.
 The 
\emph on
Tutorial
\emph default
 also contains many more examples than this section does.
\end_layout

\begin_layout Standard
A paragraph environment is simply a 
\begin_inset Quotes eld
\end_inset

container
\begin_inset Quotes erd
\end_inset

 for a paragraph which gives that paragraph certain properties.
 This can include a particular style of font, different margins, a numbering
 scheme, labels, and so on.
 Additionally, you can 
\begin_inset Quotes eld
\end_inset

nest
\begin_inset Quotes erd
\end_inset

 the different environments inside one another, allowing one environment
 to inherit some of the properties of another.
 The different paragraph environments totally replace the need for messy
 tab stops, on the fly margin adjustment, and other hangovers from the days
 of typewriters.
 There are several paragraph environments that are specific to a particular
 document type.
 We will only be covering the most common ones here.
\end_layout

\begin_layout Standard
To choose a new paragraph environment, use the pull-down box 
\begin_inset Graphics
        filename clipart/ToolbarEnvBox.png
        scale 70
        clip

\end_inset

 at the left end of the toolbar.
 \SpecialChar LyX
 will change the environment of the 
\emph on
entire
\emph default
 paragraph in which the cursor sits.
 You can also change the environment of an entire group of paragraphs if
 you select them before choosing the new environment.
 
\end_layout

\begin_layout Standard
Note that entering 
\family sans
Return
\family default
 will 
\emph on
typically
\emph default
 create a new paragraph using the 
\family sans

 We say 
\begin_inset Quotes eld

 because if you are in one of these environments:

\end_layout

\begin_layout Subsection

\end_layout

\begin_layout Standard
The default paragraph environment is 
\family sans

\family default
 for most classes.
 It creates a plain paragraph.
 If \SpecialChar LyX
 resets the paragraph environment, this is the one it chooses.
 In fact, the paragraph you're reading right now (and most of the ones in
 this manual) are in the 
\family sans
Standard
\family default
 environment.
\end_layout

\begin_layout Standard
You can nest a paragraph using the

\end_layout

\begin_layout Standard
\SpecialChar LaTeX

Quotes and Poetry

\begin_layout Standard
\SpecialChar LyX
 has three paragraph environments for writing poetry and quotations.
 They are 
\family sans
Quote
\family default
, 
\family sans
Quotation
\family default
, and 
\family sans
Verse
\family default
.
 Forget the days of changing line spacing and twiddling with margins.
 These three paragraph environments already have those changes built-in.
 They all widen the left margin and add a bit of extra space above and below
 the text they contain.
 They also allow nesting, so you can put a 
\family sans
Verse
\family default
 in a 
\family sans
Quotation
\family default
, as well as in some other paragraph environments.
\end_layout

\begin_layout Standard
There is another feature of these three paragraph environments: they do
 
\emph on
not
\emph default
 reset to 
\family sans
Standard
\family default
 when you start a new paragraph.
 So, you can type in that poem and merrily enter 
\family sans
Return
\family default
 without worrying about the paragraph environment changing on you.
 Of course, that means that, once you are done typing in that poem, you
 have to change back to the 
\family sans

\family default
 environment yourself.

Now that we've described the similarities of these three environments, it's
 time for the differences.
 
\family sans
Quote
\family default
 and 
\family sans
Quotation

 are identical except for one difference: 
\family sans
Quote
\family default
 uses extra spacing to separate paragraphs and never indents the first line.
 
\family sans
Quotation
\family default
 
\emph on
always
\emph default
 indents the first line of a paragraph and uses the same line spacing throughout.
\end_layout

\begin_layout Standard
Here's an example of the 
\family sans
Quote
\family default
 environment:
\end_layout

\begin_layout Quote
This is in the 
\family sans
Quote
\family default
 environment.
 I can keep writing, extending this line out further and further until it
 wraps.
 See – no indentation!
\end_layout

\begin_layout Quote
Here's the second paragraph of this quote.
 Again, there's no indentation, but there is extra space between me and
 the other paragraph.
\end_layout

\begin_layout Standard
Here's another example, this time in the 
\family sans
Quotation
\family default
 environment:
\end_layout

\begin_layout Quotation
This is in the 
\family sans
Quotation
\family default
 environment.
 If I keep writing, you will see the indentation.
 If your country uses a writing style that indicates new paragraphs by indenting
 the first line, then 
\family sans
Quotation
\family default
 is the environment for you! Well, you'd use it 
\emph on
if
\emph default
 you were quoting other text.
\end_layout

\begin_layout Quotation
Here's a new paragraph.
 I could ramble on and on, like a politician at election time.
 If I did that, though, you'd get bored.
\end_layout

\begin_layout Standard
As the examples show, 
\family sans
Quote
\family default
 is for those people who use extra space to separate paragraphs.
 They should put quotes in the 
\family sans
Quote
\family default
 environment.
 Those who use indentation to mark a new paragraph should use the 
\family sans
Quotation
\family default
 paragraph environment for quoted text.

 First, \SpecialChar LyX
 treats each paragraph as a list item.
 Hitting 
\family sans
Return
\family default
 does 
\emph on
not
\emph default
 reset the environment to 
\family sans
Standard
\family default
 but keeps the current environment and creates a new list item.
 The nesting depth is thereby kept.
 If you want to keep the paragraph environment but reset the current nesting
 depth, you can use 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

.
 If you do this at the top level of a list, it returns you to the 
\family sans
Standard
\family default
 environment.
\end_layout

\begin_layout Standard
You can nest lists of any type inside one another.
 In fact, \SpecialChar LyX
 changes the labels on some list items depending on how it is
 nested.
 If you intend to use any of the list paragraph environments, we suggest
 you read all of section
\begin_inset space ~

\end_layout

\begin_layout Standard
The first type of list we will describe in detail is the 
\family sans
Itemize
\family default
 paragraph environment.
 It has the following properties:
\end_layout

\begin_layout Itemize
Each item has a particular bullet or symbol as its label.
\end_layout

\begin_deeper
\begin_layout Itemize
\SpecialChar LyX
 uses the same symbol for all of the items in a given nesting level.
\end_layout

\begin_layout Itemize
The symbol appears at the beginning of the first line.
\end_layout

\end_deeper
\begin_layout Itemize
The items can have any length.
 \SpecialChar LyX
 automatically offsets the left margin of each item.
 The offset is always relative to whatever environment the 
\family sans
Itemize
\family default
 list may be in.
\end_layout

\begin_layout Itemize
If you nest an 
\family sans
Itemize
\family default
 environment inside another 
\family sans
Itemize
\family default
 environment, the label changes to a new symbol.
\end_layout

\begin_deeper
\begin_layout Itemize
There are four different symbols for up to a four-fold nesting.
\end_layout

\begin_layout Itemize
\SpecialChar LyX
 always shows the same symbol on screen.
\end_layout

\begin_layout Itemize
See section

\end_inset


\begin_inset CommandInset ref

\end_inset

 for a full explanation of nesting.
\end_layout

\end_deeper
\begin_layout Standard
Of course, that explanation was also an example of an 
\family sans
Itemize
\family default
 list.
 The 
\family sans
Itemize
\family default
 environment is best suited for lists where the order doesn't matter.
\end_layout

\begin_layout Standard
We said that different levels use different symbols as their label.
 Here's an example of all four possible symbols.
\end_layout

\begin_layout Itemize
The label for the first level 
\family sans
Itemize
\family default
 is a large black dot, or bullet.
\end_layout

\begin_deeper
\begin_layout Itemize
The label for the second level is a dash.
\end_layout

\begin_deeper
\begin_layout Itemize
The label for the third is an asterisk.
\end_layout

\begin_deeper
\begin_layout Itemize
The label for the fourth is a centered dot.
\end_layout

\end_deeper
\begin_layout Itemize
Back out to the third level.
\end_layout

\end_deeper
\begin_layout Itemize
Back to the second level.
\end_layout

\end_deeper
\begin_layout Itemize
Back to the outermost level.
\end_layout

\begin_layout Standard
These are the default labels for an 
\family sans
Itemize
\family default
 list.
 You can customize how these labels are displayed in the output in the 
\family sans
Document\SpecialChar menuseparator

\begin_layout Standard
The 
\family sans
Enumerate
\family default
 environment is used to create numbered lists and outlines.
 It has these properties:
\end_layout

\begin_layout Enumerate
Each item has a numeral as its label.
\end_layout

\begin_deeper
\begin_layout Enumerate
The label type depends on the nesting depth.
\end_layout

\end_deeper
\begin_layout Enumerate
\SpecialChar LyX
 automatically counts the items for you and updates the label as appropriate.
\end_layout

\begin_layout Enumerate
Each new 
\family sans
Enumerate
\family default
 environment resets the counter to one.
\end_layout

\begin_layout Enumerate
Like the 
\family sans
Itemize
\family default
 environment, the 
\family sans
Enumerate
\family default
 environment:
\end_layout

\begin_deeper
\begin_layout Enumerate
Offsets the items relative to the left margin.
 Items can have any length.
\end_layout

\begin_layout Enumerate
Reduces the space between items as the nesting depth increases.
\end_layout

\begin_layout Enumerate
Uses different types of labels depending on the nesting depth.
\end_layout

\begin_layout Enumerate
Allows up to a four-fold nesting.
\end_layout

\end_deeper
\begin_layout Standard
Unlike the 
\family sans
Itemize
\family default
 environment, 
\family sans
Enumerate
\family default
 shows the different labels for each item in \SpecialChar LyX
.
 Here is how \SpecialChar LyX
 labels the four different levels in an 
\family sans
Enumerate
\family default
:
\end_layout

\begin_layout Enumerate
The first level of an 
\family sans
Enumerate
\family default
 uses Arabic numerals followed by a period.
\end_layout

\begin_deeper
\begin_layout Enumerate
The second level uses lower case letters surrounded by parentheses.
\end_layout

\begin_deeper
\begin_layout Enumerate
The third level uses lower-case Roman numerals followed by a period.
\end_layout

\begin_deeper
\begin_layout Enumerate
The fourth level uses capital letters followed by a period.
\end_layout

\begin_layout Enumerate
Again, notice the decrease in the spacing between items as the nesting depth
 increases.
\end_layout

\end_deeper
\begin_layout Enumerate
Back to the third level
\end_layout

\end_deeper
\begin_layout Enumerate
Back to the second level.
\end_layout

\end_deeper
\begin_layout Enumerate
Back to the outermost level.
\end_layout

\begin_layout Standard
You can customize the type of numbering used in the 
\family sans
Enumerate
\family default
 environment, see section
\begin_inset space ~
\end_inset


\begin_inset CommandInset ref

\end_inset

.
 Such customization only shows up in the printed version, not in \SpecialChar LyX

\end_layout

\begin_layout Standard

\end_layout

\begin_layout Standard
Unlike the previous two environments, the 
\family sans
Description
\family default
 list has no fixed label.
 Instead, \SpecialChar LyX
 uses the first 
\begin_inset Quotes eld
\end_inset

word
\begin_inset Quotes erd
\end_inset

 of the first line as the label.
 Here's an example:
\end_layout

\begin_layout Description
Example: This is an example of the 
\family sans
Description
\family default
 environment.
\end_layout

\begin_layout Standard
\SpecialChar LyX
 typesets the label in boldface and puts extra space between it and the
 rest of the line.
\end_layout

\begin_layout Standard
With the first 
\begin_inset Quotes eld
\end_inset

word
\begin_inset Quotes erd
\end_inset

 it is meant that the first usage of the 
\family sans
Space
\family default
 key ends the label if you are at the beginning of the first line of an
 item.
 If you need to use more than one word in a label use a 
\family sans

\family default
.
 (Use either 
\begin_inset Info

\begin_layout Description
Usage: You should use the 
\family sans

\family default
 environment for things like definitions and theorems.
 Use it when you need to make one word in particular stand out in the text
 that describes it.
 It's not a good idea to use a 
\family sans
Description
\family default
 environment when you have an entire sentence that you want to describe.
 You're better off using 
\family sans

\family default
 or 
\family sans

 and nesting several 
\family sans

\end_layout

\begin_layout Standard
Like the 
\family sans
Description
\family default
 list the 
\family sans
Labeling
\family default
 list has user-defined labels for each list item but it provides some additional
 features.
 Here are its properties:
\end_layout

\begin_layout Labeling
\labelwidthstring 00.00.0000
item
\begin_inset space ~
\end_inset

labels \SpecialChar LyX
 uses the first 
\begin_inset Quotes eld
\end_inset

word
\begin_inset Quotes erd
\end_inset

 of each line as the item label.
 The first 
\family sans
Space
\family default
 after the beginning of the first line of an item marks the end of the label.
 If you need to use more than one word in an item label, use a protected
 space as described above.
\end_layout

\begin_layout Labeling
\labelwidthstring 00.00.0000
margins As you can see, \SpecialChar LyX
 uses different margins for the item label and the
 body of the item text.
 The body of the text has a larger left margin, which is equal to the default
 label width plus a little extra space.
 
\end_layout

\begin_layout Labeling
\labelwidthstring 00.00.0000
label
\begin_inset space ~
\end_inset

width \SpecialChar LyX
 uses the width of the label, or the default width, whatever is larger.
 If the label width is larger, the label 
\begin_inset Quotes eld
\end_inset

extends
\begin_inset Quotes erd
\end_inset

 into the first line.
 In other words, the text of the first line isn't aligned with the left
 margin of the rest of the item text.
\end_layout

\begin_layout Labeling
\labelwidthstring 00.00.0000
default
\begin_inset space ~
\end_inset

width You can set the default label width to ensure that the text of all
 items in a 
\family sans

\family default
 environment has the same left margin.
\begin_inset Newline newline
\end_inset

To change the default width, select all items in the list.
 Now open the 
\family sans

Paragraph
\begin_inset space ~
\end_inset

Settings

\end_inset

).
 The text in the box 
\family sans

\family default
 determines the default label width.
 You can use the text of your largest label here, but you can also use the
 letter 
\begin_inset Quotes eld
\end_inset

M
\begin_inset Quotes erd
\end_inset

 multiple times instead.
 M is the widest character and is a standard unit of widths in \SpecialChar LaTeX
.
 By using 
\begin_inset Quotes eld
\end_inset

M
\begin_inset Quotes erd
\end_inset

 as the unit of width you don't need to keep changing the contents of

The predefined default width is the length of 
\begin_inset Quotes eld
\end_inset

00.00.0000
\begin_inset Quotes erd
\end_inset

 (equal to 6
\begin_inset space ~

\end_layout

\begin_layout Standard
You should use the 
\family sans
Labeling
\family default
 list the same way as the 
\family sans
Description
\family default
 list: When you need one word to stand out from the text that describes
 it.
 The 
\family sans

\end_layout

\begin_layout Standard
You can nest 
\family sans

Address: An Overview
\end_layout

\begin_layout Standard
Although \SpecialChar LyX
 has document classes for letters, we've also created two paragraph
 environments called 
\family sans
Address
\family default
 and 
\family sans
Right
\begin_inset space ~
\end_inset

Address
\family default
.
 To use the letter class, you need to use specific paragraph environments
 in a specific order, otherwise \SpecialChar LaTeX
 gags on the document.
 In contrast, you can use the 
\family sans
Address
\family default
 and 
\family sans
Right
\begin_inset space ~
\end_inset

Address
\family default
 paragraph environments anywhere with no problem.
 You can even nest them inside other environments, though you can't nest
 anything in them.
\end_layout

\begin_layout Standard
Of course, you're not limited to using 
\family sans
Address
\family default
 and 
\family sans
Right
\begin_inset space ~
\end_inset

Address
\family default
 for letters only.
 
\family sans

Address

, in particular, is useful for creating article titles like those used in
 some European academic papers.
\end_layout

Usage
\begin_inset CommandInset label
LatexCommand label

\end_inset


\end_layout

\begin_layout Standard
The 
\family sans
Address
\family default
 environment formats text in the style of an address, which is also used
 for the opening and signature in some countries.
 Similarly, the 
\family sans
Right
\begin_inset space ~
\end_inset

Address
\family default
 environment formats text in the style of a right-justified address, which
 is used for the sender's address and today's date in some countries.
 Here's an example of each:
\end_layout

\begin_layout Right Address
Right Address
\begin_inset Newline newline
\end_inset

Who I am
\begin_inset Newline newline
\end_inset

Where I am
\begin_inset Newline newline
\end_inset

When is it? What is today?
\end_layout

\begin_layout Standard
That was 
\family sans
Right
\begin_inset space ~
\end_inset

Address
\family default
.
 Notice that the lines all have the same left margin, which \SpecialChar LyX
 sets to fit
 the largest block of text on a single line.
 Here's an example of the 
\family sans
Address
\family default
 environment:
\end_layout

\begin_layout Address
Who are you
\begin_inset Newline newline
\end_inset

Where do I send this
\begin_inset Newline newline
\end_inset

Your post office and country
\end_layout

\begin_layout Standard
As you can see, both 
\family sans
Address
\family default
 and 
\family sans
Right
\begin_inset space ~
\end_inset

Address
\family default
 add extra space between themselves and the next paragraph.
 If you enter 
\family sans
Return
\family default
 in either of these environments, \SpecialChar LyX
 resets the nesting depth and sets the
 environment to 
\family sans
Standard
\family default
.
 This makes sense, since 
\family sans
Return
\family default
 is the 
\family typewriter
paragraph-break
\family default
 function, and the individual lines of an address are not paragraphs.
 Thus, you have to use 
\family typewriter
break-line
\family default
 (
\begin_inset Info

arg   "newline-insert newline"
\end_inset

 or 
\family sans

\begin_layout Subsection
Academic Writing

 \SpecialChar LyX

\end_layout

\begin_layout Standard
The 
\family sans
Abstract
\family default
 environment is used for the abstract of an article.
 Technically, you could use this environment anywhere, but you really should
 only use it at the beginning of the document, after the title.
 Also, don't bother trying to nest 
\family sans
Abstract
\family default
 in anything else or 
\emph on
vice versa
\emph default
.
 It will not work.
 The 
\family sans
Abstract
\family default
 environment is only useful in the article and report document classes.
 The book document classes ignores the 
\family sans
Abstract
\family default
 completely, and it's utterly silly to use 
\family sans
Abstract
\family default
 in a letter document class.
\end_layout

\begin_layout Standard
The 
\family sans
Abstract
\family default
 environment does several things for you.
 First, it puts the centered label 
\begin_inset Quotes eld
\end_inset

Abstract
\begin_inset Quotes erd
\end_inset

 above the text.
 The label and the text of the abstract are separated by some extra vertical
 space.
 Second, it typesets everything in a smaller font, just as you'd expect.
 Lastly, it adds a bit of extra vertical space between the abstract and
 the subsequent text.
 Well, that's how it will appear on the \SpecialChar LyX
 screen.
 The actual appearance in the output depends on the document class you are
 using.
\end_layout

\begin_layout Standard
Starting a new paragraph by entering 
\family sans
Return
\family default
 does not reset the paragraph environment.
 The new paragraph will still be in the 
\family sans
Abstract
\family default
 environment.
 So, you will have to change the paragraph environment yourself when you
 finish entering the abstract of your document.

 The heading is in a large boldface font.
 Each paragraph of the

 Thus, entering

\end_inset

 (the 
\family typewriter
break-line
\family default
 function).
 
\family sans

\family default
 breaks paragraphs.
 Note, however, that 
\family sans
Return
\family default
 does not reset the paragraph environment.
 So, when you finish using the 
\family sans

\family default
 environment, you will need to change the paragraph environment yourself.
 Also, you can nest the 
\family sans

 at the beginning of a new paragraph (i.

you can't follow

\end_layout

\begin_layout Itemize
You cannot have an empty paragraph or an empty line.
 You must put at least one 
\family sans

\family default
 in any line you want blank.
 Otherwise, \SpecialChar LaTeX
 generates errors.
\end_layout

\begin_layout Itemize
You cannot get the typewriter double quotes by typing

 You get the typewriter double quotes with

Introduction
\end_layout

\begin_layout Standard
\SpecialChar LyX
 treats text as a unified block with a particular context and specific propertie
s.
 This allows you to create blocks that inherit some of the properties of
 another block.
 For example you have three main points in an outline, but point #2 also
 has two subpoints.
 In other words, you have a list inside of another list, with the inner
 list 
\begin_inset Quotes eld
\end_inset

attached
\begin_inset Quotes erd

 to item #2:
\end_layout

\begin_layout Enumerate

\begin_layout Standard
You put a list inside a list by nesting one list inside the other.
 Nesting an environment is quite simple: Select

List
\begin_inset space ~

Depth

 to change the nesting depth (the status bar will tell you how far you are
 nested).
 Instead of the menu, you can also use the toolbar buttons 
\begin_inset Info
type  "icon"
arg   "depth-increment"
\end_inset

 and 
\begin_inset Info
type  "icon"
arg   "depth-decrement"
\end_inset

 or the key bindings 
\family sans

\family default
 and 
\family sans
Shift+Tab

 or 
\begin_inset Info
type  "shortcut"
arg   "depth-increment"
\end_inset

 and 
\begin_inset Info
type  "shortcut"
arg   "depth-decrement"
\end_inset

.
 The change will work on the current selection, if you have made one (allowing
 you to change the nesting of several paragraphs at once), or the current
 paragraph.
\end_layout

\begin_layout Standard
Note that \SpecialChar LyX
 only changes the nesting depth if it can.
 If it is invalid to do so, nothing happens if you try to change the depth.
 Additionally, if you change the depth of one paragraph, it affects the
 depth of every paragraph nested inside of it.
\end_layout

\begin_layout Standard
Nesting isn't limited to lists.
 In \SpecialChar LyX
, you can nest just about anything inside anything else, as you're about
 to find out.
 This is the real power of nesting paragraph environments.
\end_layout

\begin_layout Subsection
What You Can and Can't Nest
\end_layout

\begin_layout Standard
Before we fire a list of paragraph environments at you, we need to tell
 you a little bit more about how nesting works.
\end_layout

\begin_layout Standard
The question of nesting a paragraph environment is a bit more complicated
 than a simple yes or no.
 There are three types of paragraph environments:
\end_layout

\begin_layout Itemize
Completely unnestable
\end_layout

\begin_layout Itemize
Fully nestable, you can nest them inside things and you can also nest other
 things inside them.
\end_layout

\begin_layout Itemize
A third type, you can nest them into other environments, but you can't nest
 anything into them.
\end_layout

 They are:

\begin_layout Standard
\SpecialChar LyX
 can treat these three objects as either a word or as a paragraph.
 If a figure, table, or an equation is inline, it goes wherever the paragraph
 it is in goes.
\end_layout

\begin_layout Standard
On the other hand, if you have an equation, figure or table in a 
\begin_inset Quotes eld

 You can nest it into any environment, but you obviously can't nest anything
 into it.

 So, if you nest tables, figures or equations, make sure you go to the right
 depth!
\end_layout

\begin_layout Subsection
Usage and General Features
\end_layout

\begin_layout Standard
Speaking of levels, \SpecialChar LyX
 can perform up to a six-fold nesting.
 In other words, 
\begin_inset Quotes eld
\end_inset

level #6
\begin_inset Quotes erd
\end_inset

 is the innermost possible depth.
 Here's an example to illustrate what we mean:
\end_layout

\begin_layout Enumerate
level #1 – outermost
\end_layout

\begin_deeper
\begin_layout Enumerate
level #2
\end_layout

\begin_deeper
\begin_layout Enumerate
level #3
\end_layout

\begin_deeper
\begin_layout Enumerate
level #4
\end_layout

\begin_deeper
\begin_layout Itemize
level #5
\end_layout

\begin_deeper
\begin_layout Itemize
level #6
\end_layout

\end_deeper
\end_deeper
\end_deeper
\end_deeper
\end_deeper
\begin_layout Standard
There are two exceptions to the six-fold nesting limit, and you can see
 both of them in the example.
 Unlike the other fully-nestable environments, you can only perform a four-fold
 nesting with the 
\family sans
Enumerate
\family default
 and 
\family sans
Itemize
\family default
 environments.
 For example, if we tried to nest another 
\family sans
Enumerate
\family default
 list inside item 
\begin_inset Quotes eld
\end_inset

A.
\begin_inset Quotes erd
\end_inset

, we would get errors.

\end_layout

\begin_layout Standard
The best way to explain just what you can do with nesting is by illustration.
 We have several examples of nested environments.
 In them, we explain how we created the example, so that you can reproduce
 them.
\end_layout

\begin_layout Subsubsection
Example 1: The Six-fold Way and Mixed Nesting
\end_layout

\begin_layout Labeling
\labelwidthstring MMM
#1-a This is the outermost level.
 It's a 
\family sans
List
\family default
 environment.
\end_layout

\begin_deeper
\begin_layout Labeling
\labelwidthstring MMM
#2-a This is level #2.
 We created it by using 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

 followed by 
\begin_inset Info
type  "shortcut"
arg   "depth-increment"
\end_inset

.
\end_layout

\begin_deeper
\begin_layout Labeling
\labelwidthstring MMM
#3-a This is level #3.
 This time, we just enter 
\family sans
Return
\family default
, then used 
\begin_inset Info
type  "shortcut"
arg   "depth-increment"
\end_inset

 twice in a row.
 We could have also created it the same way as we did the previous level,
 by entering 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

 followed by 
\begin_inset Info
type  "shortcut"
arg   "depth-increment"
\end_inset

.
\end_layout

\begin_deeper
\begin_layout Standard
This is actually a 
\family sans
Standard
\family default
 environment, nested inside of 
\begin_inset Quotes eld
\end_inset

#3-a
\begin_inset Quotes erd
\end_inset

.
 So, it's at level #4.
 We did this by entering 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

, then 
\begin_inset Info
type  "shortcut"
arg   "depth-increment"
\end_inset

, then changing the paragraph environment to 
\family sans
Standard
\family default
.
 Do this to create list items with more than one paragraph — it also works
 for the 
\family sans
Description
\family default
, 
\family sans
Enumerate
\family default
, and 
\family sans
Itemize
\family default
 environments!
\end_layout

\begin_layout Standard
Here's another 
\family sans
Standard
\family default
 paragraph, also at level #4, made with just a 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

.
\end_layout

\begin_layout Labeling
\labelwidthstring MMM
#4-a This is level #4.
 We enter 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

 and changed the paragraph environment back to 
\family sans
List
\family default
.
 Remember — we can't nest anything inside a 
\family sans
Standard
\family default
 environment, which is why we're still at level #4.
 However, we 
\emph on
can
\emph default
 keep nesting things inside 
\begin_inset Quotes eld
\end_inset

#3-a
\begin_inset Quotes erd
\end_inset

.
\end_layout

\begin_deeper
\begin_layout Labeling
\labelwidthstring MMM
#5-a This is level #5\SpecialChar ldots

\end_layout

\begin_deeper
\begin_layout Labeling
\labelwidthstring MMM
#6-a \SpecialChar ldots
and this is level #6.
 By now, you should know how we made these two.
\end_layout

\end_deeper
\begin_layout Labeling
\labelwidthstring MMM
#5-b Back to level #5.
 Just enter 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

 followed by a 
\begin_inset Info
type  "shortcut"
arg   "depth-decrement"
\end_inset

.
\end_layout

\end_deeper
\begin_layout Labeling
\labelwidthstring MMM
#4-b After another 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

 followed by a 
\begin_inset Info
type  "shortcut"
arg   "depth-decrement"
\end_inset

, we're back at level #4.
\end_layout

\end_deeper
\begin_layout Labeling
\labelwidthstring MMM
#3-b Back to level #3.
 By now it should be obvious how we did this.
\end_layout

\end_deeper
\begin_layout Labeling
\labelwidthstring MMM
#2-b Back to level #2.
 
\end_layout

\end_deeper
\begin_layout Labeling
\labelwidthstring MMM
#1-b And last, back to the outermost level, #1.
 After this sentence, we will enter 
\family sans
Return
\family default
 and change the paragraph environment back to 
\family sans
Standard
\family default
 to end the list.
\end_layout

\begin_layout Standard
We could have also used the 
\family sans
Description
\family default
, 
\family sans
Quote
\family default
, 
\family sans
Quotation
\family default
, or even the 
\family sans
Verse
\family default
 environment in place of the 
\family sans
List
\family default
 environment.
 The example would have worked exactly the same.
\end_layout

\begin_layout Subsubsection
Example 2: Inheritance
\end_layout

\begin_layout LyX-Code
This is the LyX-Code environment, at level #1, the outermost
\end_layout

\begin_layout LyX-Code
level.
  Now we will enter 
\family sans
Return
\family default
, then 
\begin_inset Info
type  "shortcut"
arg   "depth-increment"
\end_inset

, after
\begin_inset Newline newline
\end_inset

which, we will change to the 
\family sans
Enumerate
\family default
 environment.
\end_layout

\begin_deeper
\begin_layout Enumerate
This is the 
\family sans
Enumerate
\family default
 environment, at level #2.
\end_layout

\begin_layout Enumerate
Notice how the nested 
\family sans
Enumerate
\family default
 not only inherits its margins from its parent environment (
\family sans
LyX-Code
\family default
), but also inherits its font and spacing!
\end_layout

\end_deeper
\begin_layout Standard
We ended this example by entering 
\family sans
Return
\family default
.
 After that, we needed to reset the paragraph environment to 
\family sans
Standard
\family default
 and reset the nesting depth by using 
\begin_inset Info
type  "shortcut"
arg   "depth-decrement"
\end_inset

 once.
\end_layout

\begin_layout Subsubsection
Example 3: Labels, Levels, and the

\end_layout

\end_inset


\end_layout

\begin_layout Enumerate
This is level #1, in an 
\family sans
Enumerate
\family default
 paragraph environment.
 We're actually going to nest a bunch of these.
\end_layout

\begin_deeper
\begin_layout Enumerate
This is level #2.
 We used 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

 followed by 
\begin_inset Info
type  "shortcut"
arg   "depth-increment"
\end_inset

.
 Now, what happens if we nest an 
\family sans
Itemize
\family default
 environment inside of this one? It will be at level #3, but what will its
 label be? An asterisk?
\end_layout

\begin_deeper
\begin_layout Itemize
No! It's a bullet.
 This is the 
\emph on
first
\emph default
 
\family sans
Itemize
\family default
 environment, even though it's at level #3.
 So, its label is a bullet.
 (We got here by using 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

, then 
\begin_inset Info
type  "shortcut"
arg   "depth-increment"
\end_inset

, then changing the environment to 
\family sans
Itemize
\family default
.)
\end_layout

\begin_deeper
\begin_layout Itemize
Here's level #4, produced using 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

, then 
\begin_inset Info
type  "shortcut"
arg   "depth-increment"
\end_inset

.
 We will do that again\SpecialChar ldots

\end_layout

\begin_deeper
\begin_layout Enumerate
\SpecialChar ldots
to get to level #5.
 This time, however, we also changed the paragraph environment back to 
\family sans
Enumerate
\family default
.
 Notice the type of numbering, it is 
\emph on
lowercase Roman
\emph default
, because we are in the 
\emph on
thirdfold
\emph default
 
\family sans
Enumerate
\family default
 environment (that is, it is an 
\family sans
Enumerate
\family default
 inside an 
\family sans
Enumerate
\family default
 inside an 
\family sans
Enumerate
\family default
).
\end_layout

\begin_layout Enumerate
What happens if we 
\emph on
don't
\emph default
 change the paragraph environment, but decrease the nesting depth? What
 type of numbering does \SpecialChar LyX
 use?
\end_layout

\begin_layout Enumerate
Oh, as if you couldn't guess by now, we're just using 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

 to keep the current environment and depth but create a new item.
\end_layout

\begin_layout Enumerate
Let's use 
\begin_inset Info
type  "shortcut"
arg   "depth-decrement"
\end_inset

 to decrease the depth after the next 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

.
\end_layout

\end_deeper
\begin_layout Enumerate
This is level #4.
 Look what type of label \SpecialChar LyX
 is using!
\end_layout

\end_deeper
\begin_layout Enumerate
This is level #3.
 Even though we've changed levels, \SpecialChar LyX
 is still using a lowercase Roman numeral
 as the label.Why?
\end_layout

\begin_layout Enumerate
Because, even though the nesting depth has changed, the paragraph is 
\emph on
still
\emph default
 a thirdfold 
\family sans
Enumerate
\family default
 environment.
 Notice, however, that \SpecialChar LyX
 
\emph on
did
\emph default
 reset the counter for the label.
\end_layout

\end_deeper
\begin_layout Enumerate
Another 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

 
\begin_inset Info
type  "shortcut"
arg   "depth-decrement"
\end_inset

 sequence, and we're back to level #2.
 This time, we not only changed the nesting depth, but we also moved back
 into the twofold-nested 
\family sans
Enumerate
\family default
 environment.
\end_layout

\end_deeper
\begin_layout Enumerate
The same thing happens if we do another 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break inverse"
\end_inset

 
\begin_inset Info
type  "shortcut"
arg   "depth-decrement"
\end_inset

 sequence and return to level #1, the outermost level.
\end_layout

\begin_layout Standard
Lastly, we reset the environment to 
\family sans
Standard
\family default
.
 As you can see, the level number doesn't correspond to what type of labeling
 \SpecialChar LyX
 uses for the 
\family sans
Enumerate
\family default
 and 
\family sans
Itemize
\family default
 environments.
 The number of other 
\family sans
Enumerate
\family default
 environments surrounding it determines what kind of label \SpecialChar LyX
 uses for an
 
\family sans
Enumerate
\family default
 item.
 The same rule applies for the 
\family sans
Itemize
\family default
 environment, as well.
\end_layout

\begin_layout Subsubsection

 It does not only separate the list but also creates a new one outside the

Inside nested environments, it is also possible to split the outer environment
\change_unchanged

\end_layout

\begin_layout Standard
By right-clicking on a separator one can change it into a paragraph separator
 (red arrow in LyX).
 The difference between both separator types is that the plain separator
 only splits the list and not the current paragraph.

In general, you get an environment separator when you press

What is a space? While you might be used to pressing the space key anytime
 you want to separate two words in ordinary word processors, \SpecialChar LyX
 offers you
 more spaces: spaces of different widths and spaces which can or cannot
 be broken at the end of a line.
 The following sections will show you some examples where those spaces are
 useful.

With the introduction of typewriters, it became conventional in some countries
 to type two spaces after a period to mimic the wider spaces used by typesetters
 at the ends of sentences.
 There is no need to do this as \SpecialChar LyX
 automatically takes care about this.
 However, you do not want an end of sentence space after an abbreviation
 followed by a period; see section

Horizontal fills (HFills) are a special \SpecialChar LyX
 feature for adding extra space

 An HFill is actually a variable length space, whose length always equals
 the remaining space between the left and right margins.
 If there is more than one HFill on a line, they divide the available space
 equally between themselves.

Sometimes you want to insert space with exactly the length of a phrase.
 For example, you want to create the following multiple choice question:
\end_layout

What is correct English?:
\begin_inset Newline newline
\end_inset

so that the choices appear exactly after the phrase 
\begin_inset Quotes eld
\end_inset

Mr.
\begin_inset space ~
\end_inset

Edge
\begin_inset space ~
\end_inset


\begin_inset Quotes erd
\end_inset

.
 To get this, you can use the phantom insets available via the menu 
\family sans
Insert\SpecialChar menuseparator
Formatting\SpecialChar menuseparator
Phantom
\family default
.
 In our case insert a horizontal phantom at the beginning of the last two
 lines and insert 
\begin_inset Quotes eld
\end_inset

Mr.
\begin_inset space ~
\end_inset

Edge
\begin_inset space ~
\end_inset


\begin_inset Quotes erd
\end_inset

 into the phantom inset (note the space after 
\begin_inset Quotes eld
\end_inset

Edge
\begin_inset Quotes erd

).
 A phantom insets prints only the space of its content (like a placeholder).
 That is why it is named 
\begin_inset Quotes eld
\end_inset

phantom
\begin_inset Quotes erd
\end_inset

.
 The normal phantom outputs the width and height of the content as space,
 while the horizontal and vertical variant only outputs the corresponding
 dimension.

\begin_layout Standard
If you don't like the way \SpecialChar LaTeX
 does the page breaks in your document, you can
 force a page break where you want one.
 Normally this will not be necessary, because \SpecialChar LaTeX
 is good at page breaking.
 Only if you use a lot of

\end_layout

\begin_layout Standard
We recommend you not to use forced page breaks until the text is finished

\emph on

\end_layout

\begin_layout Standard
There are two types of page breaks: One that ends the page without any special
 action.
 This can be inserted above or below a paragraph via the menu 
\family sans
Insert\SpecialChar menuseparator
Formatting\SpecialChar menuseparator

 The second type, that is inserted via the menu 
\family sans
Insert\SpecialChar menuseparator
Formatting\SpecialChar menuseparator
Page
\begin_inset space ~
\end_inset

Break
\family default
, ends a page but stretches the content of the page, so that it fills out
 the complete page.
 This type is useful to avoid whitespace when a page break produces a page
 on which only the last few lines are absent.
\end_layout

\begin_layout Standard
You might try to use a page break to ensure that a figure or table appears
 at the top of a page.
 This is, of course, the wrong way to do it.
 \SpecialChar LyX
 gives you a way of automatically ensuring that your figures and tables
 appear at the top of a page (or the bottom, or on their own page) without
 having to worry about what precedes or follows your figure or table.

\begin_layout Plain Layout
Fonts ! Vector-
\end_layout

\end_inset

 are built from outlines of the single glyphs (e.
\begin_inset space \thinspace{}
\end_inset

g.
 characters) in the font.
 This means that each glyph is defined using mathematical curves that are
 well suited for scaling to any requested size.
 This mathematical definition is interpreted by the font renderer and the
 curve is filled out with pixels according to the size and glyph.
 This means that vector fonts will look pretty good in all sizes.
 Only at very small sizes where each pixel has to be very carefully computed
 to provide a good image might it be hard to provide a good rendering.
\begin_inset Newline newline
\end_inset

That could mean that one only needs to define one font size and scale them.
 But to achieve a better quality, many fonts define several font sizes.
 That improves the appearance because you need more details at large font
 sizes than at small ones.
\begin_inset Newline newline

The font types

\begin_layout Plain Layout
Fonts ! Bitmap-

\end_inset

 on the other hand, are defined by bitmap graphics from the start; so they
 will look good at all the sizes they are meant for.
 However, they don't scale well, because in order to scale a glyph, each
 pixel is enlarged into several pixels.
 It is the same effect that happens if you try to enlarge a picture in an
 image manipulation program.
 In order to mitigate this effect, bitmap fonts are typically provided in
 several fixed sizes typically from around 8
\begin_inset space ~
\end_inset

pixels high up to 34
\begin_inset space ~
\end_inset

pixels or so high in steps according to what is believed to be useful.
 The advantage of bitmap fonts is that no complicated computations are necessary
 to display each glyph; so bitmap fonts display therefore more quickly than
 scalable fonts.
 The disadvantage is that sizes that don't exist as fixed versions have
 to be scaled by doubling pixels, and thus look bad.
\begin_inset Newline newline
\end_inset

Bitmap fonts are named 
\family typewriter

\family default
 in PostScript- and PDF-documents.
\end_layout

\begin_layout Standard
The result of all this is that bitmap fonts are best for the size they are
 designed for, while scalable fonts are good for nearly all sizes.
 So one needs fewer font size definitions for scalable fonts.
 That's the reason why nearly all text rendering and typesetting programs
 use scalable fonts.
\end_layout

\begin_layout Standard
To see which fonts are used in a PDF-document, look at its document properties.
\end_layout

\begin_layout Standard
Many modern typesetting and markup languages have begun to move towards
 specifying character styles rather than specifying a particular font.
 For example, instead of changing to an italicized version of the current
 font to emphasize text, you use an 
\begin_inset Quotes eld
\end_inset

emphasized style
\begin_inset Quotes erd
\end_inset

 instead.
 This concept fits in perfectly with \SpecialChar LyX
.
 In \SpecialChar LyX

 details.

\end_layout

\begin_layout Standard
Traditionally, \SpecialChar LaTeX
 used its own fonts.
 That is to say, you cannot directly access the fonts installed on your
 operating system, but you have to use specific fonts provided by your \SpecialChar LaTeX

 distribution.
 The reason is that \SpecialChar LaTeX
 needs some extra information about the fonts, which
 have to be provided by additional files and packages.
 The downside of this is that your font choice is somewhat limited compared
 to a word processor.
 On the other hand this comes with the advantage that the provided fonts
 are generally of very good quality, and that \SpecialChar LaTeX
 files are very portable across
 different machines.
 Also, the range of fonts supported by traditional \SpecialChar LaTeX
 has increased a lot
 in the meantime; so you can find packages for many free and commercial
 fonts.
 \SpecialChar LyX
 supports the fonts that are under a free license via the user interface
 (see section
\begin_inset space ~
\end_inset


\begin_inset CommandInset ref
LatexCommand ref
reference "subsec:Document-Font"

\end_inset

 for details).
 Other fonts are available if you enter the relevant \SpecialChar LaTeX
 code in the document
 preamble (please refer to the documentation of your desired font).
\end_layout

\begin_layout Standard
Recent developments brought some new \SpecialChar LaTeX
 engines that are also able directly
 to access fonts that are installed for your operating system, namely Xe\SpecialChar TeX

 and Lua\SpecialChar TeX
.
 Both engines are supported by \SpecialChar LyX
.
 By using them, you can theoretically use any OpenType or TrueType font
 that is installed on your system.
 The next section describes how to use these fonts.

\begin_layout Standard
As we've already seen, \SpecialChar LyX
 automatically changes the character style for certain
 paragraph environments.
 \SpecialChar LyX
 supports two character styles, 
\family sans
Emphasized
\family default
 and 
\family sans
Noun
\family default
.
 You can activate both of these styles via key bindings, the menus, and
 the toolbar.
\end_layout

\begin_layout Standard
To activate the 
\family sans
Noun
\family default
 style, do one of the following:
\end_layout

\begin_layout Itemize
click on the toolbar button 
\begin_inset Info
type  "icon"
arg   "font-noun"
\end_inset


\end_layout

\begin_layout Itemize
use the key binding 
\begin_inset Info
type  "shortcut"
arg   "font-noun"
\end_inset


\end_layout

\begin_layout Standard
These commands are all toggles.
 That is, if 
\family sans
Noun
\family default
 style is already active, they deactivate it.
\end_layout

\begin_layout Standard
One typically uses the 
\family sans
Noun
\family default
 style for proper names.

\end_layout

\begin_layout Standard
A more widely used character style is the 
\family sans

\family default
 style.
 You can activate (or deactivate — it's also a toggle) the 
\family sans
Emphasized
\family default
 style by:
\end_layout

\begin_layout Itemize
clicking on the toolbar button 
\begin_inset Info
type  "icon"

\end_layout

\begin_layout Itemize
using the keybindings 
\begin_inset Info

\end_layout

\begin_layout Standard
Normally the

 use a different font.
\end_layout

\begin_layout Standard
We've been using the

 Here's one more example:

There are always occasions when you will need to do some fine-tuning; so
 \SpecialChar LyX

 Also, writers sometimes use a different font to offset a character's thoughts

Text

 the property to be removed.
 If you, for example, apply a style with properties A, B and C to text that
 currently has font properties B, C, F and G, and if B is set to toggle
 and C is set not to toggle, the text ends up with properties A, C, F and
 G.

 For the properties on the left side of the dialog (

DVI files do not contain images, they only link to them.
 So don't forget to deliver the images together with your DVIs.

 If you copy consecutive hyphens, by contrast, they are output as consecutive
 hyphen characters.
 An unintended consequence of this change was that all dashes now were output
 as non-breakable dashes.
 Since furthermore, in order to maintain the output, occurrences of consecutive
 hyphens in documents that were saved by \SpecialChar LyX

\begin_inset space ~

2.1 or earlier versions, were converted to literal en- and em-dash characters,
 respectively, these were output to \SpecialChar LaTeX

 Abbreviations get the same amount of space after the period that a word
 gets after another word.

By default, the quotation mark styles are persistent.
 That is to say, a quotation mark maintains the style that was current when
 it was inserted, even if the document-wide style changes.
 This allows you to enter marks of different style.
 If you check the setting

, however, special quotation marks will be inserted (in the LyX window,
 they appear in a special color).
 These marks will automatically adapt to the main style (and its changes).
 Such quotation marks make it easy to alter the quotation mark style in
 one step (e.
\begin_inset space \thinspace{}

g., if your publisher requests a different style).
\end_layout

\begin_layout Standard
Individual quotation marks (i.

\end_inset


\end_layout

\begin_layout Standard
In the early days of word processors, page breaks went wherever the page
 happened to end.
 There was no regard for what was actually going on in the text.
 For example the heading for a new section was printed at the very bottom
 of the page, the first line of a new paragraph all alone at the bottom
 of a page, or the last line of a paragraph at the top of a new page.
 These bits of text became known as 
\emph on
widows
\emph default
 and 
\emph on
orphans
\emph default
.
\end_layout

\begin_layout Standard
Clearly, \SpecialChar LyX
 can avoid breaking pages after a section heading.
 That's part of the advantage of paragraph environments.
 But what about widows and orphans, where the page breaks leave one line
 of a paragraph all alone at the top or bottom of a page? There are rules
 built into \SpecialChar LaTeX
 governing page breaks, and some of those rules are there specifical
ly to prevent widows and orphans.
 If they appear nevertheless and you don't like them, you can add the commands
\begin_inset Newline newline
\end_inset


\series bold

\backslash
widowpenalty=10000
\begin_inset Newline newline
\end_inset


\backslash
clubpenalty=10000

\begin_layout Standard
Each image can define a new group of image settings or join an existing
 group.
 Images within such a group share their settings, so adjusting one image
 of the group automatically also adjusts all other images of the group in
 the same way.
 So you can for example change the size for a bunch of images without the
 need to manually change each of them.

 A dialog will appear, asking you for the number of rows and columns.
 The default table has lines around any cell and the first row appears separated
 from the rest of the table.
 This separation appears due to a double line: The cells of the first row
 have a line below them and the cells of the second row have a line above
 them.

Table Dialog
\end_layout

\begin_layout Standard
You can alter a table by clicking on it with the right mouse button and
 then choosing 
\family sans
More\SpecialChar menuseparator
Settings
\family default
.
 This brings up the table dialog.
 Here you can adjust the settings of the cell, row and/or column where the
 cursor is placed currently.
 Most of the dialog options also work on selections.
 This means that if you select more cells, columns or rows the action is
 done on all of your selection.
\end_layout

\begin_layout Standard
In addition to the table dialog, the 
\family sans
table
\begin_inset space ~
\end_inset

toolbar
\family default

 It appears if the cursor is inside a table.
\end_layout

\begin_layout Standard
In the tab 
\family sans
Table
\begin_inset space ~
\end_inset

Settings
\family default
 of the table dialog you can set the alignment for the current row.
 If you add a row or column, it will be inserted right beside or below the
 current cell respectively.
 The vertical alignment of a column can only be adjusted when a column width
 is given.
 A given width will allow the cell to have line breaks and multiple paragraphs
 of text, see section
\begin_inset space ~

You can mark multiple cells of one row/column as a multicolumn/row cell
 using the check box

Multicolumn
\family default
 or

.
 This will merge the cells to 
\emph on
one

 cell, spread over more than one column/row.
 Multicolumn cells are treated as own rows, so that the alignment, width,
 and border settings affect only the multicolumn cell.
 Here is an example table with a multicolumn cell in the first row and one
 in the last row without the upper border:

\begin_layout Standard
A table cell can contain text, inline equations, a figure, or another table.
 All these kinds of objects can be placed in the same cell.
 Font sizes and shapes can also be altered.
 But you can't put a special environment in a cell (like 
\family sans
Section*
\family default
, etc.), nor set spacing options for the cell's paragraph.
\end_layout

\begin_layout Standard
To have multi-line entries in table cells, you have to declare a fixed width
 for the column in the table dialog.
 Your text is then automatically split into multiple lines and the cell
 is enlarged vertically when the length of the text exceeds the given width.
 An example:

Introduction
\end_layout

\begin_layout Standard
A float is a block of text associated with some sort of label, which doesn't
 have a fixed location.
 It can 
\begin_inset Quotes eld

float
\begin_inset Quotes erd
\end_inset

 forward or backward a page or two, to wherever it fits best.
 
\family sans
Footnotes
\family default

\family sans
Margin
\begin_inset space ~
\end_inset

Notes
\family default
 are also floats, because they can float to the next page when there are
 too many notes on the current page.
\end_layout

\begin_layout Standard
Floats make it possible to get a high quality layout.
 Images and tables can be distributed evenly over the pages to avoid whitespace
 and pages without text.
 As the floating often destroys the spatial context between the text and
 the image/table, every float can be referenced in the text.
 Floats are therefore numbered.
 Referencing is described in section

\begin_layout Standard
To insert a float, use the menu

 A box with a caption will be inserted into your document.
 The label will automatically be translated to the document language in
 the output.
 After the label you can insert the caption text.

 The image or table is inserted above or below the caption in a separate
 paragraph within the float.
 To keep your \SpecialChar LyX
-document readable, you can open and close the float box by
 left-clicking on the box label.
 A closed float box looks like this:

 that can occur when the surrounding text is specially formatted.

Cross-Reference
\family default
 (toolbar button 
\begin_inset Info
type  "icon"
arg   "dialog-show-new-inset ref"
\end_inset

).
 It is important to use cross-references to figure floats rather than using
 vague references like 
\begin_inset Quotes eld
\end_inset

the figure above
\begin_inset Quotes erd
\end_inset

, because, as \SpecialChar LaTeX
 will reposition the floats in the final document, it might
 not be 
\begin_inset Quotes eld

above
\begin_inset Quotes erd
\end_inset

 at all.

\begin_layout Standard
Normally only one image is inserted in a figure float, but sometimes you
 might want to use two images with separate subcaptions.
 This can be done by inserting image floats into existing image floats.
 Note that only the main caption of the float is added to the List of Figures
 as described in section

To create a math formula, you can just click on the toolbar icon 
\begin_inset Info
type  "icon"
arg   "math-mode on"
\end_inset

 (shortcut 
\begin_inset Info
type  "shortcut"
arg   "math-mode"
\end_inset

).
 That will create a little blue rectangle, with purple markers around its
 corners.
 That blue rectangle is the formula itself; the purple markers indicate
 what level of nesting within the formula you are at.
 You can also choose a particular formula type to insert via the 
\family sans

\begin_layout Standard
Editing the parameters of a formula and adding math constructs can be done

, that appears if the cursor is in a formula.
\end_layout

\begin_layout Standard
There are two main types of formulas, inline formulas and display formulas.
 Inline formulas appear within a text line, like this one:
\end_layout

\begin_layout Standard
This is a line with an inline formula 
\begin_inset Formula $A=B$
\end_inset

 in it.
\end_layout

\begin_layout Standard
Displayed formulas appear outside the text like if they were in a separate
 paragraph, like this one:
\begin_inset Formula 
\[
A=B
\]

\end_inset

You can only number and reference displayed formulas.
\end_layout

\begin_layout Standard
\SpecialChar LyX
 also supports many \SpecialChar LaTeX
 math commands.
 For example, typing 
\begin_inset Quotes eld
\end_inset


\series bold

\backslash
alpha
\series default

\begin_inset Quotes erd
\end_inset

, followed by a space, in a formula will create the Greek letter 
\begin_inset Formula $\alpha$

\begin_layout Standard
The best control over the cursor position within an existing formula is
 achieved with the arrow keys.
 \SpecialChar LyX
 uses small rectangles to indicate places where something can be inserted.
 The arrow keys can be used to navigate between parts of a formula.
 Pressing 
\family sans
Space
\family default
 will leave a formula construct (a square root 
\begin_inset Formula $\sqrt{2}$
\end_inset

, or parentheses 
\begin_inset Formula $\left(f\right)$
\end_inset

, or a matrix 
\begin_inset Formula $\left[\begin{array}{cc}
1 & 2\\
3 & 4
\end{array}\right]$
\end_inset

).
 Pressing 
\family sans
Escape
\family default
 will leave the formula, placing the cursor after the formula.

 cells of a matrix or the positions in a multi-line equation.

\family default
, printed in this document as 
\begin_inset Quotes eld
\end_inset


\begin_inset space \textvisiblespace{}
\end_inset


\begin_inset Quotes erd

, seems to do nothing in a formula, since it does not add a space between
 characters, but it does exit a nested structure.
 For this reason, you have to be careful about using 
\family sans
Space
\family default
.
 For example, if you want 
\begin_inset Formula $\sqrt{2x+1}$
\end_inset

, type 
\series bold

\backslash
sqrt
\begin_inset space \textvisiblespace{}
\end_inset

2x+1
\series default
 and not 
\series bold

\backslash
sqrt
\begin_inset space \textvisiblespace{}
\end_inset

2x
\begin_inset space \textvisiblespace{}
\end_inset

+1
\series default
, since in the latter case only the 
\family typewriter

\begin_inset Formula $2x$
\end_inset


\family default
 will be under the square root sign: 
\begin_inset Formula $\sqrt{2x}+1$
\end_inset

.
\end_layout

\begin_layout Standard
You can leave many parts of a formula, like this matrix, partially filled
 in, such as:
\begin_inset Formula 
\[
\left(\begin{array}{ccc}
\lambda_{1}\\
 & \ddots\\
 &  & \lambda_{n}
\end{array}\right)
\]

\end_inset

If you leave a fraction only partially filled in, or a subscript with nothing
 in it, the results will be unpredictable, but most constructs don't mind.
\end_layout

Selecting Text
\end_layout

\begin_layout Standard
You can select text within a formula in two different ways.
 Place the cursor at one end of the string of text you want, and press 
\family sans
Shift
\family default
 and a cursor movement key to select text.
 It will be highlighted as with regular text selection.
 Alternatively, you can select text with the mouse in the usual way.
 That text can then be cut or copied, and then pasted within any formula,
 but not in a normal text region in \SpecialChar LyX

\series bold
x^2
\begin_inset space \textvisiblespace{}

 The final

 puts the cursor back down on the base line of the expression.
 If you type

\begin_inset Formula $x^{2}y$
\end_inset

, type 
\series bold

 If you use characters in the superscript, that could be accented with the
 circumflex 
\begin_inset Quotes eld

Integral signs, however, will place the limits to the side in both formula

In a formula you can insert accented characters in the same way as in text
 mode.
 This may depend on your keyboard, or the bindings file you use.
 You can also use \SpecialChar LaTeX
 commands, for example, to enter 
\begin_inset Formula $\hat{a}$
\end_inset

 even if your keyboard doesn't have the circumflex enabled.
 Our example is entered by typing

\begin_layout Standard
There are several brackets available through \SpecialChar LyX
.
 For some purposes, using just the keys 
\family typewriter
[]{}()|<>
\family default
 should suffice.
 But if you want to surround a large structure, like a matrix or a fraction,
 or if you have several layers of brackets, it is better to use the math
 toolbar delimiter icon 
\begin_inset Info
type  "icon"
arg   "dialog-show mathdelimiter"
\end_inset

.
 For example, if you construct the brackets around a matrix in this way:
\begin_inset Formula 
\[
\left[\begin{array}{cc}
1 & 2\\
3 & 4
\end{array}\right]
\]

\end_inset

it makes it easier to see the layers of parentheses.
 Below, the expression on the left was entered using the delimiter icon
 
\begin_inset Info
type  "icon"
arg   "dialog-show mathdelimiter"
\end_inset

 and the expression on the right was entered using the 
\family typewriter
()
\family default
 keys.
 
\begin_inset Formula 
\[
\frac{1}{\left(1+\left(\frac{1}{1+\left(\frac{1}{1+x}\right)}\right)\right)}\qquad\qquad\frac{1}{(1+(\frac{1}{1+(\frac{1}{1+x})}))}
\]

\end_inset


\end_layout

If you use the delimiter icon, the parentheses, and other brackets from
 that menu will automatically re-size to accommodate the size of what is
 inside.
\end_layout

\begin_layout Standard
To construct brackets click on the button for the bracket you want on the
 left side and right side.
 If you use the option

, the selected bracket type will be used for the left and the right side.
 The selection will be shown as \SpecialChar TeX
 code.
 If you want one side not to have a bracket, use 
\family sans
(none)
\family default
.
 It will appear in \SpecialChar LyX
 with a dotted line, but nothing will be printed.
\end_layout

\begin_layout Standard
If you want to place brackets around existing math structures, like a square
 root, you can do so by first highlighting (selecting) the structure that
 is to go inside the brackets.
 Then choose the appropriate brackets for left and right and click on 
\family sans
Insert
\family default
.
 The most common bracket combinations (parentheses, square brackets, and
 braces, on both sides) can be entered more quickly using keyboard shortcuts.
 For example, to insert a pair of parentheses, select the structure and
 enter 
\begin_inset Info
type  "shortcut"
arg   "math-delim ( )"

 For example, the sequence

 means that the first column will be left-justified, the second will be

 in a non-empty formula, the part before the relation sign (equal sign

 is in the second column, and the rest in the third column.
 A new row is created by every further entry of 
\begin_inset Info

 Multi-line formulas are always displayed formulas.

Math ! Font sizes
\end_layout

\end_inset


\end_layout

\begin_layout Standard
There are four font styles (relative sizes) used in math-mode, which are
 automatically chosen in most situations.
 These are called 
\family sans
textstyle
\family default
, 
\family sans
displaystyle
\family default
, 
\family sans
scriptstyle
\family default
, and 
\family sans
scriptscriptstyle
\family default
.
 For most characters, 
\family sans
textstyle
\family default
 and 
\family sans
displaystyle
\family default
 are actually the same size, but fractions, superscripts and subscripts,
 and certain other structures, are set larger in 
\family sans
displaystyle
\family default
.
 Except for some operators, which resize themselves to accommodate various
 situations, all text will be set in the styles that \SpecialChar LaTeX
 thinks are appropriate.
 These choices can be overridden by using the math panel button 
\begin_inset Info
type  "icon"
arg   "math-insert \\style"
\end_inset

.
 A box for the size will be created in which you can insert the math structure.
 For example, you can set 
\begin_inset Formula $\frac{1}{2}$
\end_inset

, which is normally in 
\family sans
textstyle
\family default
, larger in 
\family sans
displaystyle
\family default
: 
\begin_inset Formula ${\displaystyle \frac{1}{2}}$
\end_inset

.
 The four styles are used in the following example:
\end_layout

\begin_layout Standard
\begin_inset Formula $displaystyle$
\end_inset

, 
\begin_inset Formula ${\textstyle textstyle}$
\end_inset

, 
\begin_inset Formula ${\scriptstyle scriptstyle}$
\end_inset

, 
\begin_inset Formula ${\scriptscriptstyle scriptscriptstyle}$
\end_inset

.
\end_layout

\begin_layout Standard
All these math-mode font sizes are relative so that if the whole math inset
 is set in a particular size with the menu 
\family sans
Edit\SpecialChar menuseparator
Text
\begin_inset space ~
\end_inset

Style
\family default
, all sizes in the formula will be adjusted relative to this size.
 Similarly, if the base font size of the document is changed, all fonts
 will be adjusted to correspond.
 As an example here is a formula in the font size 
\begin_inset Quotes eld
\end_inset

\begin_layout Standard
One of \SpecialChar LyX
's strengths is cross-references.
 You can reference every section, float, footnote, formula, and list in
 the document.
 To reference a document part, you have to insert a label into it.
 The label is used as an anchor and a name for the reference.
 We want for example to refer to the second item of the following list:
\end_layout

\begin_layout Enumerate
First item
\end_layout

\begin_layout Enumerate
\begin_inset CommandInset label
LatexCommand label
name "enu:Second-item"

\end_inset

Second item
\end_layout

\begin_layout Enumerate
Third item
\end_layout

\begin_layout Standard
First we insert a label into the second item with the menu 
\family sans
Insert\SpecialChar menuseparator
Label
\family default
 or by pressing the toolbar button 
\begin_inset Info
type  "icon"
arg   "label-insert"
\end_inset

.
 A gray label box like this: 
\begin_inset Graphics
        filename clipart/label.png

\end_inset

 is inserted and the label window pops up asking for the label text.
 \SpecialChar LyX
 offers as text the first words of the item with a prefix, in our case
 the text 
\begin_inset Quotes eld
\end_inset


\family sans
enu:Second-item
\family default

\begin_inset Quotes erd
\end_inset

.
 The prefix 
\begin_inset Quotes eld
\end_inset


\family sans
enu:
\family default

\begin_inset Quotes erd
\end_inset

 stands for 
\begin_inset Quotes eld
\end_inset

enumerate
\begin_inset Quotes erd
\end_inset

.
 The prefix depends on the document part where the label is inserted; for
 example, if you insert a label into a section heading, the suggested prefix
 will be 
\begin_inset Quotes eld
\end_inset


\family sans
sec:
\family default

\begin_inset Quotes erd
\end_inset

.
\end_layout

\begin_layout Standard
To reference the item, we refer to its label using the menu

Insert\SpecialChar menuseparator
Cross-Reference
\family default
 or the toolbar button 
\begin_inset Info
type  "icon"
arg   "dialog-show-new-inset ref"
\end_inset

.
 A gray cross-reference box like this: 
\begin_inset Graphics
        filename clipart/reference.png

\end_inset

 is inserted and the cross-reference window appears showing all the labels
 in the document.
 We can now sort the labels alphabetically and then choose the entry 
\begin_inset Quotes eld
\end_inset


\family sans

\family default

 At the position of the cross-reference box the item number will appear

 between the cross-reference name and the cross-reference to avoid ugly

\end_layout

\begin_layout Standard
There are eight formats of cross-references:
\end_layout

\begin_layout Description
<reference>: prints the number, this is the default: 
\begin_inset CommandInset ref
LatexCommand ref
reference "fig:Two-images"

\end_inset


\end_layout

\begin_layout Description
(<reference>): prints the number within two parentheses, this is the style
 normally used to reference formulas, especially when the reference name
 
\begin_inset Quotes eld

Equation
\begin_inset Quotes erd
\end_inset

 is omitted: 
\begin_inset CommandInset ref
LatexCommand eqref
reference "eq:tanhExp"

\end_inset


\end_layout

\begin_layout Description
<page>: prints the page number: Page
\begin_inset space ~
\end_inset


\begin_inset CommandInset ref
LatexCommand pageref
reference "fig:Two-images"

\end_inset


\end_layout

\begin_layout Description

\begin_inset space ~

page
\begin_inset space ~

<page>: prints the text “on page” and the page number: 
\begin_inset CommandInset ref
LatexCommand vpageref
reference "fig:Two-images"

\end_inset


\begin_inset Newline newline
\end_inset

If the label is on the same page, it prints “on this page”; if the label
 is on a facing page in a two-sided document, it prints “on the facing page”;
 if it is on the previous page which is not a facing page, it prints “on
 the previous page”; if it is on the next page which is not a facing page,
 it prints “on the next page”.
 The wording of the printed text also depends on the used document class.
\end_layout

\begin_layout Description
<reference>

 The package

 The format is specified by using the command 
\series bold

newrefformat
\series default
 (prettyref) or 
\series bold

newref
\series default
 (refstyle) in the \SpecialChar LaTeX

 For example redefining all references to figures (which have the label

\begin_inset Quotes eld
\end_inset


\family sans

) can be done for

\end_inset


\series bold

\backslash
newref{fig}{refcmd={Image on page 
\backslash

\series default

\begin_inset Newline newline
\end_inset

Note that neither 
\series bold
prettyref
\series default
 nor 
\series bold
refstyle 
\series default
predefines reference formats for all available types.
 This is especially true for the wide variety of mathematical `theorem'
 environments.
 So if you want to make formatted references to, say, Propositions, then
 you will need to define the relevant format yourself.
 For 
\series bold
prettyref
\series default
, you might do so as follows:
\begin_inset Newline newline
\end_inset


\series bold

\backslash
newrefformat{prop}{Proposition 
\backslash
ref{#1}}
\series default

\begin_inset Newline newline
\end_inset

 the package documentation 
\begin_inset CommandInset citation

\begin_inset CommandInset ref

, which is described in the following section (but see also sec.
\begin_inset space ~
\end_inset


\begin_inset CommandInset ref

).
 If you want anything other than the numerical citations that are used in
 this document, such as author-year citations, and if you have more than
 a handful of references, then you should seriously consider
\emph on
 
\emph default
using a bibliography database.
\end_layout

\begin_layout Standard
In order to demonstrate the difference between these two approaches, we
 use two bibliographies in this document, a 
\family sans
Bibliography
\family default
 environment and a database-generated bibliography.
 As you can see, the bibliography that is created from a database lists
 only the database entries that are referenced in the document.
 In other words, the database approach relieves you, amongst other things,
 from the burden to check which entries you have actually cited.

 If you click on it, you will get a dialog in which you can set a 
\family sans

\family default
 and a 
\family sans

\family default
.
 The key is the symbolic name by which you will refer to this bibliography
 entry.
 Each entry needs to be given a unique key, which is one word consisting
 of ASCII characters only.

\end_layout

\end_inset

 It also makes it very easy to have a uniform layout for all bibliography
 entries.
 You can collect the bibliography of all relevant books and articles of
 your working field in a database.
 This database can be used for different documents, and by default only
 the entries cited in a particular document will appear in the bibliography
 list for that document.
 This relieves you of the need to keep track of which articles and books
 you have cited.

The database is a text file with the file extension 
\begin_inset Quotes eld

 and in the \SpecialChar LaTeX
 books (

 Bib\SpecialChar TeX

Bibliography Processors

\begin_layout Standard
To generate the bibliography from a database, \SpecialChar LyX
 uses a bibliography processor,
 that is an external program that reads the database, sorts the citations
 and processes the data in a way it can be included in the document.
 The classic program is called Bib\SpecialChar TeX
.
 It has the advantage that it is very mature and widespread, but the disadvantag
e that it has severe limitations, due to its age.
\end_layout

\begin_layout Standard
Meanwhile, some alternatives have been developed that address some of these
 limitations.
 LyX natively supports some of them and lets you select a custom processor.
 You can do this on a general level in

 Note that for the 
\family sans
Biblatex
\family default

 workarea.
 Whether the output uses numerical, author-year or another format such as
 alpha-numerical depends only on the selected

\family default
.
 However, when switching between Author-year and Author-number, a suitable
 style is proposed.
 With 
\family sans

 style.
\end_layout

\begin_layout Standard
For any author-year and author-numerical selection, multiple style variants
 are available in the 
\family sans

\family default

 Some selections also provide further options like the option to uppercase
 a name prefix such as 
\begin_inset Quotes eld
\end_inset

\begin_inset Quotes erd
\end_inset

 (to 
\begin_inset Quotes eld

\begin_layout Standard
In the citation dialog you can also set text to appear after a citation
 reference, e.
\begin_inset space \thinspace{}
\end_inset

page numbers, which will then be formatted according to the style's needs
 (e.

\end_inset

with or without 
\begin_inset Quotes eld
\end_inset

Text
\begin_inset space ~
\end_inset

before
\family default
 and 
\family sans

 Here is a simple example where the text

 appears after the reference:
\end_layout

\end_inset

.
\end_layout

\begin_layout Standard
All styles except for 
\family sans
Basic (BibTeX)
\family default
 also provide the feature to add text that precedes the reference (such
 as 
\begin_inset Quotes eld
\end_inset

cf.
\begin_inset Quotes erd
\end_inset

).
 This text is then also included in the parentheses, if the style requires
 this.
\end_layout

\begin_layout Standard
Note that these pre- and postnotes apply to the whole citation.
 So if you refer to multiple references at once, the prenote will precede
 the first citation in the list, the postnote will follow the last.
 Some 
\family sans
Biblatex
\family default
 styles allow to add pre- and postnotes to any individual reference in a
 multi-citation (so-called 
\begin_inset Quotes eld
\end_inset

qualified citation lists
\begin_inset Quotes erd
\end_inset

).
 \SpecialChar LyX
 supports this.
 If you use such a style and if the current reference includes multiple
 items the

 We want to group for example the index entries for itemized and enumerated

\begin_inset Quotes eld
\end_inset

 To achieve this, we use the command
\end_layout

\begin_layout Standard

\series bold

\end_layout

\begin_layout Standard
In our case we want to have 
\begin_inset Quotes eld

maison
\begin_inset Quotes erd

 after 
\begin_inset Quotes eld
\end_inset

maïs
\begin_inset Quotes erd
\end_inset

 and write therefore for the index entry of maison:
\end_layout

\begin_layout Standard

\series bold
maïs@maison
\end_layout

\begin_layout Standard
The previous entry need not be a real existing entry.
 You can also use another word to tell \SpecialChar LaTeX

 You can also format the page number using the character

 If you use

\end_layout

\end_inset


\end_layout

\begin_layout Standard
In general, we encourage you to not format page numbers directly as shown
 above.
 Instead, you should define a macro in the preamble and use that.
 Maybe you want all page references italic that refer to a definition of
 the indexed term, so that users can easily find definitions.
 If so, put the following in the preamble
\end_layout

\begin_layout Standard

\series bold

\backslash
newcommand{
\backslash
IndexDef}[1]{
\backslash
textit{#1}}
\end_layout

\begin_layout Standard
and write
\end_layout

\begin_layout Standard

\series bold

\end_layout

\begin_layout Standard
in the index entry.
\begin_inset Index idx
status open

\begin_layout Plain Layout
Dummy entries ! my entry|IndexDef
\end_layout

\end_inset

 The advantage is that, if you change your mind later or if your publisher
 insists that definitions must not be italic but bold, you just need to
 change the macro in the preamble, not every single index entry.
\end_layout

\begin_layout Standard
You can also change the layout for the whole index.
 For example, we marked the index list box of this document as bold to get
 a bold font for all index entries.

 that it was developed with only the English language in mind.

 To add further indexes, add the name of the index (in the form that should
 also appear as a heading) to the 
\family sans

\family default
 input field and press the 
\family sans

 button.
 The new index now also appears in the list.
 If you like, you can attribute an alternative \SpecialChar LyX

Once the document changes have been applied, you can find the new index
 list in 
\family sans
Insert\SpecialChar menuseparator
List/TOC
\family default

\family sans
Insert

 menu has a separate entry for each of the defined indexes.
 The workflow is basically the same as for the default index, but there
 are additional features:
\end_layout

\begin_layout Itemize
If you want to change the attribution of a specific index entry, right-clicking
 on the entry's label will open a dialog where you can do that.
\end_layout

\begin_layout Itemize
By right-clicking on an index, you can change its type.
 Furthermore, you can specify an index to be a 
\family sans
Subindex
\family default
.
 If you do that, the heading of that list will be decreased by one level.
 For example, if you use a book class, where the standard index heading
 is defined as a chapter, subindexes will be defined as sections and can
 thus be nested to the non-subindexes.
\end_layout

\begin_layout Itemize
The option 
\family sans

 state (whether the content of the branch is shown in the output or not),
 its background color inside \SpecialChar LyX
 and whether the name of the branch should
 be appended to the document file name on export if the branch is active
 (see below for an example).
 Furthermore, the dialog lets you merge two branches (just rename one branch

As \SpecialChar LyX
 uses \SpecialChar LaTeX
 in the background, it supports many \SpecialChar LaTeX
 commands and constructs,
 but not all.
 \SpecialChar LaTeX
 contains hundreds of packages that provide different commands.
 All the time packages are being updated and new ones added.
 This has the advantage that you can typeset nearly everything as there
 is a \SpecialChar LaTeX
-package for every problem, though \SpecialChar LyX
 cannot support all packages and
 their commands.
\end_layout

\begin_layout Standard
But don't worry, you can use any \SpecialChar LaTeX
-command directly in \SpecialChar LyX
 inside the \SpecialChar TeX

 box.
 A \SpecialChar TeX
 Code box is created by the menu 
\family sans

\family default
 or by the toolbar button

 The box can be opened by left-clicking and closed by right-clicking on
 it and selecting 
\family sans

\end_layout

\begin_layout Standard
You can insert complete or incomplete commands as \SpecialChar TeX
 Code.
 Incomplete means that the command argument can be Standard \SpecialChar LyX
 text.
 For example, if you want to draw a frame around a word
\begin_inset Foot

\begin_layout Plain Layout
The LyX way would be to use a framed box.
\end_layout

\end_inset

 and are therefore using the \SpecialChar LaTeX
-command 
\series bold

, you can write the command part 
\series bold

fbox{

 in a \SpecialChar TeX

\series bold

\series default
 in a second \SpecialChar TeX

 The word between the two \SpecialChar TeX

 following example:

\begin_layout Standard
When you write larger documents or books, you will need to know something
 about the \SpecialChar LaTeX
-commands that \SpecialChar LyX
 uses in the background.
 Because \SpecialChar LaTeX
 is based on commands, you can 
\begin_inset Quotes eld
\end_inset

program
\begin_inset Quotes erd
\end_inset

 your text.
 This has the advantage that the layout of the document can be changed at
 any time if you know the right commands.
 For example, imagine you have to write a manual for a product and the deadline
 is the end of the day.
 Your boss has just complimented you for your good work but wants to have
 all caption labels bold.
 But you have over a hundred figure and table captions with non-bold labels
 in your manual.
 Of course it is impossible to change all caption labels manually in one
 day.
\end_layout

\begin_layout Standard
Now \SpecialChar LaTeX
 comes into play.
 As mentioned above, for every problem there exists a \SpecialChar LaTeX
-package.
 First you have to find out which and therefore look in the \SpecialChar LaTeX
 package database,
 
\begin_inset CommandInset citation
LatexCommand cite
key "Catalogue"
literal "true"

\end_inset

.
\end_layout

\begin_layout Standard
As result you find that the package 
\series bold
caption
\series default

\begin_inset Index idx
status collapsed

\begin_layout Plain Layout
\SpecialChar LaTeX
 packages ! caption
\end_layout

\end_inset

 is what you need.
 To use a package, you have to load it in the document preamble (menu 
\family sans
Document\SpecialChar menuseparator
Settings
\family default
\SpecialChar menuseparator

\family sans
LaTeX
\begin_inset space ~
\end_inset

Preamble
\family default
) with the command
\end_layout

\begin_layout Standard

\series bold

\backslash
usepackage[options]{package name}
\end_layout

\begin_layout Standard
All \SpecialChar LaTeX
 commands begin with a backslash, the command argument is set within
 two braces and the options are set within two brackets.
 Note that not all commands have an argument and options.
\end_layout

\begin_layout Standard
In your case the package name is 
\series bold
caption
\series default
.
 After a look in the documentation of the package, you know that the option
 
\series bold
labelfont=bf
\series default
 will change the font of all caption labels to bold.
 So you add the command
\end_layout

\begin_layout Standard

\series bold

\backslash
usepackage[labelfont=bf]{caption}
\end_layout

\begin_layout Standard
to the preamble and the problem is solved.
\begin_inset Foot

\begin_layout Plain Layout
For more commands provided by the 
\series bold

\series default
 package, have a look at its documentation, 
\begin_inset CommandInset citation
LatexCommand cite
key "caption"
literal "true"

\end_inset

.
\end_layout

\end_inset


\end_layout

\begin_layout Standard
Note that some document classes have built-in solutions for well-known problems
 like your case.
 For example if you use a 
\family sans
KOMA-Script
\family default
 class, you don't need the package 
\series bold
caption
\series default
, you can instead write
\end_layout

\begin_layout Standard

\series bold

\backslash
setkomafont{captionlabel}{
\backslash
bfseries}
\end_layout

\begin_layout Standard
in the preamble and the problem is solved.
 So if you plan to write a large document, you should have a look at the
 documentation of the document class you want to use.
 (
\series bold

\backslash
setkomafont
\series default
 is an example of a command with more than one argument.)
\end_layout

\begin_layout Standard
Commands in the preamble affect the whole document, while commands in the
 text affect only the text after the command or only the text used as command
 argument.
 To insert a \SpecialChar LaTeX
-command in text, use the \SpecialChar TeX
 Code box as described in the previous
 section.

Definition
\end_layout

\begin_layout Standard
To define your header line, add all three header environments.
 The things you add to each environment appear on odd numbered pages, the
 things in the optional arguments on even numbered pages.
 For single-sided documents, the optional arguments will not be used and
 can be omitted.
 If you leave a header environment or its argument empty, nothing appears
 in the output.
 Defining the footer line works similarly.
\end_layout

Default header/footer
\end_layout

\begin_layout Standard
The custom header/footer is not empty by default.
 The default header contains the chapter and section title and the center
 footer has the page number.
 In order to remove unwanted entries from the header/footer, include the
 relevant header/footer style in your document, but leave it blank.
 So, if you do not want a page number in the footer, include a blank

Appearance
\end_layout

\begin_layout Standard
The header and footer will appear on normal pages.
 Some pages are different.
 The title page has a header/footer environment of its own, and so does
 any page that starts a new part or chapter in your book.
 Such pages will not have the custom headers/footers, but that is normal.
 There is for example no need to print a header with the chapter name on
 the chapter page where the chapter heading is in big bold letters anyway.

In case you need more than one text line as a header/footer, you can do
 this by adding a ragged line break in the style definition.
 However, the default height of the header/footer is only the height of
 one text line.
 To expand the height, redefine the \SpecialChar LaTeX

Selected document parts
\end_layout

\begin_layout Standard
Besides math there are other cases where you might like to see a preview,
 for example things that \SpecialChar LyX
 cannot render like rotated parts or things that
 are not yet supported by \SpecialChar LyX
.
 To do this, insert a preview inset via the menu 
\family sans
Insert\SpecialChar menuseparator
Preview
\family default
.
 Insert or paste the stuff that you want to preview into this inset.
 The preview will be generated when the cursor is outside the preview inset.
 If you click on the preview, you can edit the previewed stuff.
\end_layout

\begin_layout Standard
An example: To create rotated boxes, you use the \SpecialChar LaTeX
 command 
\series bold

\backslash
rotatebox
\series default
 which is not yet supported by \SpecialChar LyX
.
\begin_inset Foot

\end_layout

\end_inset

 Instead of the \SpecialChar TeX
 Code boxes you want to see in \SpecialChar LyX
 the final rotated boxes,
 for example to adjust the rotation angle to fit with the surrounding text.
 Therefore you create a preview inset and copy the text with the rotated
 boxes into it.
 Here is the result:

If \SpecialChar LyX
 does not show a preview, make sure that you enabled previews as described
 above and also make sure that \SpecialChar TeX
 Code in the preview inset is valid and that
 you loaded the \SpecialChar LaTeX
 packages in your document preamble that are required by
 the \SpecialChar TeX
 Code.
 If \SpecialChar LyX
 cannot create a preview, you will in most cases also not be able to
 view your document due to \SpecialChar LaTeX
 errors.
 So if you have to use some \SpecialChar TeX
 Code and don't know if it is correct, the preview
 inset is a nice method to check it without the need to view the whole document.

 You can also select document parts in \SpecialChar LyX

 (when it is more than one paragraph) is shown as source code.
 To view the whole document as source, enable the corresponding option in
 the source view window.
 If you check

\begin_layout Subsection
Introduction
\end_layout

\begin_layout Standard
The advanced find and replace feature of \SpecialChar LyX
 allows for searching of complex,
 format-sensitive text segments and mathematics contents within \SpecialChar LyX
 documents.
 It is an enhancement of the standard (quick) find and replace feature.
 The key-features are:
\end_layout

\begin_layout Itemize
Both searching of text and of mathematical formulas is allowed, where the
 latter is done by entering mathematics in the usual way; not only entire
 mathematical formulas are found, but also parts occurring within more complex
 formulas
\end_layout

\begin_layout Itemize
Search may be format-insensitive, so that the searched text is found in
 any context/style (standard text, section headings, notes, and even mathematics
), or it may be format-sensitive, so that, for example, a word entered with
 a section heading will only be found within section headings
\end_layout

\begin_layout Itemize
Search may be restricted to mathematics environments only; this is useful
 for remangling math notation where one does not want to match any text
 outside of mathematics environments
\end_layout

\begin_layout Itemize
Search may be widened to a specific 
\emph on
scope
\emph default
, i.
\begin_inset space \thinspace{}
\end_inset

e.
\begin_inset space ~
\end_inset

a set of files which may be all the children of the document being edited,
 all the open files, or all the manuals available from the 
\family sans
Help
\family default
 menu
\end_layout

\begin_layout Itemize
Replace may optionally preserve capitalization, so that the replaced text
 capitalization is adapted to the matching text (i.
\begin_inset space \thinspace{}
\end_inset

e.
\begin_inset space ~
\end_inset

all lowercase, all uppercase, first letter uppercase followed by lowercase)
\end_layout

\begin_layout Subsection
Basic usage
\end_layout

\begin_layout Standard
The advanced find and replace feature is activated through the menu 
\family sans

\end_inset

.
 This opens the 
\family sans

\end_layout

\begin_layout Subsubsection
Searching for text
\end_layout

\begin_layout Standard
Enter into the 
\family sans
Find
\family default
 \SpecialChar LyX
 mini-editor a simple word, and search for occurrences of it by clicking
 on the 
\family sans
Find
\begin_inset space ~
\end_inset

Next
\family default
 button at the bottom of the dialog (or just press the 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break"
\end_inset

 key).
 The entered word is found both in text mode and in math mode, and in emphasized
, bold or normal face, and in both in section titles and in standard text.
 Pressing 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break"
\end_inset

 repeatedly keeps searching forward while pressing 
\family sans
Shift+Return
\family default
 searches backwards.
\end_layout

\begin_layout Standard
The 
\family sans
Case
\begin_inset space ~
\end_inset

sensitive
\family default
 option allows matches to occur only with the same case as entered in the
 
\family sans
Find
\family default
 editor.
 The 
\family sans
Whole
\begin_inset space ~
\end_inset

words
\family default
 option allows matches to occur only at word boundaries.
\end_layout

\begin_layout Subsubsection
Searching for mathematics
\end_layout

\begin_layout Standard
Mathematical formulas, such as 
\begin_inset Formula $x^{2}$
\end_inset

 or something more complex like 
\begin_inset Formula $\frac{x^{2}}{1+x^{2}}$
\end_inset

, may be searched for by typing them in the 
\family sans
Find
\family default
 editor.
 When searching for a formula, it is found both when it is alone and when
 it occurs in sub-formulas and nested parts of sub-formulas.
 For example the mentioned segments would be found in something like 
\begin_inset Formula $\frac{x^{2}}{\sqrt{\frac{x^{2}}{1+x^{2}}}}$
\end_inset

.
\end_layout

\begin_layout Subsubsection
Style-aware search
\end_layout

\begin_layout Standard
It is also possible to search for text with specific styles.
 This is done by switching to the 
\family sans
Settings
\family default
 tab of the dialog and unchecking the 
\family sans
Ignore format
\family default
 option.
 This way, entering in the 
\family sans
Find
\family default
 editor
\end_layout

\begin_layout Itemize
a normal word and searching for it would not find instances of the word
 occurring in emphasized or boldface.
\end_layout

\begin_layout Itemize
an emphasized or boldface word and searching for it would find the respective
 instances with the same face only, and within the same text style only.
\end_layout

\begin_layout Itemize
a normal word in a section heading, and searching for it, would find occurrences
 of it only within section headings.
 Also, if the text to search is given an emphasized or bold face, in addition
 to a section style, then it is found only when occurring with the same
 style.
\end_layout

\begin_layout Itemize
a displayed formula will only find instances of this formula that are also
 displayed formulas (and not inline formulas).
\end_layout

\begin_layout Subsubsection
Replace
\end_layout

\begin_layout Standard
The entries made in the 
\family sans
Find
\family default
 editor can be replaced with entries made in the 
\family sans
Replace
\begin_inset space ~
\end_inset

 In order to find the next occurrence and replace it, click on the 
\family sans
Replace
\family default
 button or alternatively press 
\begin_inset Info
type  "shortcut"
arg   "paragraph-break"
\end_inset

 or 
\family sans
Shift+Return
\family default
 while the cursor is in the 
\family sans
Replace
\begin_inset space ~
\end_inset

with
\family default

\end_layout

\begin_layout Standard
You can replace with fully-featured formatted \SpecialChar LyX
 entries.
 Typical scenarios in which to use this capability might be (just to mention
 two):
\end_layout

\begin_layout Itemize
replacing occurrences of a word with a customized formatted version of the
 same word, for example replacing occurrences of a name like 
\begin_inset Quotes eld
\end_inset

func()
\begin_inset Quotes erd
\end_inset

 with its typewriter version 
\begin_inset Quotes eld
\end_inset


\family typewriter
func()
\family default

\begin_inset Quotes erd
\end_inset


\end_layout

\begin_layout Itemize
performing a notation rework of mathematical symbols, for example replacing
 occurrences of 
\begin_inset Quotes eld
\end_inset


\begin_inset Formula $R$
\end_inset


\begin_inset Quotes erd
\end_inset

 with 
\begin_inset Quotes eld
\end_inset


\begin_inset Formula $\mathbb{R}$
\end_inset

 letters occurring in normal text), or occurrences of 
\begin_inset Formula $x_{j}^{i}$
\end_inset

 with 
\begin_inset Formula $x_{i,\,j}$
\end_inset

, or occurrences of 
\begin_inset Formula $x[k]$
\end_inset

 with 
\begin_inset Formula $x_{k}$
\end_inset

.
\end_layout

\begin_layout Subsection
Advanced usage
\end_layout

\begin_layout Standard
There is a regular expression (regexp) based searching facility.
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
A good explanation of regular expressions is given in this Wikipedia entry:
 
\begin_inset CommandInset href
LatexCommand href
target "https://en.wikipedia.org/wiki/Regular_expression"
literal "false"

\end_inset

.
\end_layout

\end_inset

 You can search for a regular expression by inserting a regexp inset into
 the 
\family sans
Find
\family default
 editor.
 This is done with the context menu 
\family sans
Insert\SpecialChar menuseparator
Insert Regular Expression
\family default
 while the cursor is in the 
\family sans
Find
\family default
 editor.
 Characters entered within regexp insets are matched according to the regular
 expression matching rules
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
Under the constraint that any (sub)expression must match a well-formed \SpecialChar LyX

 segment, i.
\begin_inset space \thinspace{}
\end_inset

e.
\begin_inset space ~
\end_inset

when matching \SpecialChar LaTeX
 code, no segments with unbalanced {} braces are allowed to
 match expressions.
\end_layout

\end_inset

, while text entered outside regexp insets is matched exactly against the
 same text in the document.
 You can cut and paste regexp-mode insets.
 Examples of using such a feature may be:
\end_layout

\begin_layout Enumerate
Searching for all fractions with a given denominator: for example, entering
 in the 
\family sans
Find
\family default
 editor the fraction 
\begin_inset Formula $\frac{.*}{1+x^{2}}$
\end_inset

 (where the 
\begin_inset Formula $.*$
\end_inset

 on the numerator is the match-everything regular expression) finds all
 fractions with the given denominator.
\end_layout

\begin_layout Enumerate
Searching for all text with a given style: for example, after unchecking
 the 
\family sans
Ignore format
\family default
 option from the 
\family sans
Settings
\family default
 tab, entering a 
\series bold

\begin_inset Formula $.*$
\end_inset


\series default
 regular expression and giving it an emphasized or bold face, finds all
 emphasized or bold face text respectively.
 Also, by inserting a 
\begin_inset Formula $.*$
\end_inset

 regular expression in a bullet or enumerated list or a section heading,
 you can find all bullet or enumerated lists or section headings.
\end_layout

\begin_layout Standard
Finally, references to (sub)expressions in regexp may be used as usual:
 Enclosing parts of the expression within round braces 
\begin_inset Formula $()$
\end_inset

, and referring back to them through 
\begin_inset Formula $\backslash1$
\end_inset

, 
\begin_inset Formula $\backslash2$
\end_inset

, etc..
 For example, try searching with the regexp
\begin_inset Newline newline
\end_inset

[[:space:]]([[:alpha:]]+)[[:space:]]
\backslash
1[[:space:]]
\begin_inset Newline newline
\end_inset

in order to find word repetitions, if there are any.
\end_layout

\begin_layout Standard
The usage of back references in the replaced text is not (yet) implemented.
\end_layout

\begin_layout Standard
\begin_inset Note Greyedout

\begin_layout Plain Layout

\series bold
Note:

 Back references work both when occurring within the same regexp, and when
 occurring in multiple different regexps, where the numbering of back-referenced
 sub-expressions is absolute.
 That is,
\begin_inset space ~
\end_inset


\begin_inset Formula $\backslash1$
\end_inset

 always refers to the first occurrence of 
\begin_inset Formula $()$
\end_inset

 in all entered regexps.

 start the spell checking from either the current cursor position or the
 beginning of the currently selected text.
 A sidebar will appear showing any incorrect (or unknown) word found, allowing
 you to edit and replace it in a second line.
 Whenever an unknown word is found, the word is highlighted and the text
 scrolled so that it is visible.
 In the spellchecker sidebar, there is a box showing suggestions for a correctio
n, if any could be found.
 Clicking on one of the corrections will copy it to the

Using the thesaurus
\end_layout

\begin_layout Standard
To start the thesaurus, use the menu 
\family sans
Tools\SpecialChar menuseparator
Thesaurus
\family default
 or the toolbar button 
\begin_inset Info
type  "icon"
arg   "thesaurus-entry"
\end_inset

 while the cursor is at the word you want to look up or while a word is
 selected.
 A dialog pops up showing you probably related words that you can use as
 a replacement.
 The suggestions are grouped into categories.
 Note that, for some languages (such as English), the thesaurus does not
 only show equivalent words (synonyms), but also generic terms (such as
 
\emph on
organism
\emph default
 for 
\emph on
plant
\emph default
), related terms (such as 
\emph on
political
\begin_inset space ~
\end_inset

theory
\emph default
 for 
\emph on
anarchistic
\emph default
), compounds (such as 
\emph on
tree
\begin_inset space ~
\end_inset

diagram
\emph default
, if you look for 
\emph on
tree
\emph default
) and opposites (antonyms) (such as 
\emph on
girl
\emph default
 for 
\emph on
boy
\emph default
).
 Generic terms, related terms and antonyms are marked as such.
\end_layout

\begin_layout Standard
The language is automatically chosen from the language at the cursor, but
 you can also switch it in the dialog, as you can enter new words to look
 up directly there.
\end_layout

\begin_layout Standard
Note that the thesaurus cannot handle phrases (only compounds that are in
 the dictionary, such as the above 
\emph on
tree diagram
\emph default
), and you have to use the so called lemma form, i.
\begin_inset space \thinspace{}
\end_inset

e.
\begin_inset space \space{}
\end_inset

the form that is used in the dictionaries (for many languages: first person
 singular indicative active for nouns, infinitive for verbs).
 For example, looking up the word form 
\emph on
reporting
\emph default
 yields no results, while results are shown for the word form 
\emph on
report
\emph default
.
 Your best bet is to highlight only the relevant part of such a word (e.
\begin_inset space \thinspace{}
\end_inset

g.
\begin_inset space \space{}
\end_inset


\emph on
report
\emph default
 in 
\emph on
report
\emph default
s); then you will get suggestions without needing to adjust the query in
 the dialog, and also the replacement will probably be correct (as only
 the highlighted part will be replaced; thus the ending remains).

Language ! Encoding
\end_layout

\end_inset


\end_layout

\begin_layout Standard
The document language and quote styles are set here.
 The encoding specifies how the document content is exported to \SpecialChar LaTeX
 (the \SpecialChar LyX
 file
 is always encoded in utf8).
 All characters that cannot be encoded using the specified encoding will
 be exported as \SpecialChar LaTeX
-commands (this can fail if a \SpecialChar LaTeX
-command is not known for
 a particular character).
\end_layout

\begin_layout Standard
If you use the option 
\family sans
Language Default
\family default
, \SpecialChar LyX
 determines the encoding of a text part from the language of this text.
 If the document contains text in more than one language you may get more
 than one encoding in the \SpecialChar LaTeX
 file.
 If you do not use this option then the complete document will always use
 exactly one encoding.
 Checking this option is the preferred setting.
\end_layout

\begin_layout Standard
\SpecialChar LyX
 also supports Unicode output, which is particularly useful if you need
 lots of special symbols or non-alphabetic scripts, respectively.
 If you want to use this (and your \SpecialChar LaTeX
 installation supports Unicode), choose
 one of the four utf8 variants from the list below.
 Unfortunately the Unicode support of standard \SpecialChar LaTeX
 is quite incomplete, so
 it is not uncommon that a file with lots of Unicode symbols works fine
 with 
\family sans
Language Default
\family default
 (when \SpecialChar LyX
 uses its list of known \SpecialChar LaTeX
-commands), but does not work with a fixed
 utf8 encoding (when the list of known \SpecialChar LaTeX
-commands is not used, because all
 Unicode symbols can be encoded in utf8).
 The situation is much better with Xe\SpecialChar TeX
 and Lua\SpecialChar TeX
, two new alternative engines
 to standard \SpecialChar LaTeX
.
 Both engines support Unicode natively.
 \SpecialChar LyX
 now also supports these two engines (via the output formats 
\family sans

\begin_inset space ~

(XeTeX)
\family default
, 
\family sans

, see section
\begin_inset space ~
\end_inset


\begin_inset CommandInset ref
LatexCommand ref
reference "subsec:Output-file-formats"

).
 So if you are using many special or accented characters and 
\family sans
Language Default
\family default
 fails, you might try out one of these new engines.
\end_layout

\begin_layout Standard

 systems.
\end_layout

\begin_layout Standard
There are also binding files designed for special document classes, like
 
\shape italic
broadway.bind
\shape default
, and binding files for special languages.
 The names of language binding files begin with a language code, e.
\begin_inset space \thinspace{}
\end_inset

g.
\begin_inset space \space{}
\end_inset


\begin_inset Quotes eld
\end_inset

pt
\begin_inset Quotes erd

 for Portuguese.
 If you use \SpecialChar LyX
 in a certain language, \SpecialChar LyX
 will try to use the appropriate binding
 file.
\end_layout

\begin_layout Standard
Some binding files, like 
\shape italic
math.bind

, only have a limited scope.
 When looking at the end of the file 
\shape italic

\end_layout

\begin_layout Standard
To add new or modify existing key bindings to your own taste you can use
 the table in the dialog that lists all \SpecialChar LyX
 functions and the bound shortcuts.
 To find functions easily, they are grouped by categories and the dialog
 provides the field 
\family sans
Show key-bindings containing
\family default
.
 In this field you can insert a keyword for a function you want to edit.
 Insert there for example as keyword 
\begin_inset Quotes eld
\end_inset

paste
\begin_inset Quotes erd
\end_inset

 and you get the four different existing shortcuts for the three different
 functions that contain 
\begin_inset Quotes eld
\end_inset

paste
\begin_inset Quotes erd
\end_inset

 in their name.
 As you can see, one function can have more than one shortcut.
 All \SpecialChar LyX
 functions are also listed in the file 
\family sans
\SpecialChar LyX
 Functions
\family default
 that you will find in the 
\family sans
Help
\family default
 menu.
\end_layout

\begin_layout Standard
For example, to add the shortcut 
\family sans
Alt+Q
\family default
 for the function 
\family sans
textstyle-apply
\family default
, select the function and press the 
\family sans
Modify
\family default
 button.
 A dialog pops up where you can add the shortcut by using it.
 So press Alt+Q to define the shortcut.
\end_layout

\begin_layout Standard
Modifying an existing shortcut is done the same way.
 You can also bind multiple functions to one shortcut by starting the \SpecialChar LyX
 Function
 definition with “command alternatives” and following it with the different
 function names as a semicolon separated list.
 \SpecialChar LyX
 will then use the first function that is enabled in the current document
 part.
 
\end_layout

\begin_layout Standard
If you don't like a particular shortcut, you can remove it.
\end_layout

\begin_layout Standard
Alternatively you can also edit shortcuts by modifying binding files with
 a text editor.
 The syntax of the entries is:
\end_layout

\begin_layout Standard

\series bold

\backslash
bind 
\begin_inset Quotes eld
\end_inset

key combination
\begin_inset Quotes erd
\end_inset

 
\begin_inset Quotes eld
\end_inset

\SpecialChar LyX
 function
\begin_inset Quotes erd
\end_inset


\end_layout

\begin_layout Standard
Note, though, that the key combination definition uses a specific syntax.
 This applies to the designators of specific modifier keys (e.
\begin_inset space \thinspace{}
\end_inset

g., 
\family typewriter
M
\family default
, 
\family typewriter
S
\family default
, 
\family typewriter
C
\family default
 for 
\family sans
Meta/Alt
\family default
, 
\family sans
Shift
\family default
, 
\family sans
Ctrl
\family default
, respectively) as well as to the other keys.
 Note particularly that you cannot use non-alphanumeric characters directly
 in the definition of the key combination, but must use commands following
 the Xlib standard instead (please refer to the existing bind files for
 a model).
 So if you wanted to bind a command to the key combination 
\family sans
Alt+Shift+:
\family default
, you needed to specify it as 
\family typewriter
M-S-colon
\family default
.
 If you use the dialog to edit key bindings, you don't have to care for
 these specifics.
 \SpecialChar LyX
 transforms your input to the correct syntax.

 This prefix includes by default the document directory (represented by
 a single dot '.').
 The prefix can contain any list of paths separated by the default separator
 of the OS (':' on UNIX like systems and ';' on Windows).
 If files are included, the paths listed in the TEXINPUTS prefix will be
 scanned for the input files.
 Note that any non-absolute path listed in the TEXINPUTS prefix is considered
 to be relative to the directory of your \SpecialChar LyX

 It is recommended that you always include '.' as one of the paths; otherwise
 compilation may fail for some documents.
