21 /* InsetInfo displays shortcuts, lyxrc, package and textclass
22 availability and menu information in a non-editable boxed InsetText.
24 Output of such an inset may vary from system to system, depending
25 on LyX and LaTeX configurations. Two LyX help files, LaTeXConfig.lyx
26 and Shortcuts.lyx make heavy use of this inset. The former uses it
27 to display the availability of packages and textclasses, the latter
28 uses it to display currently used shortcuts.
30 This inset has two arguments: the type and argument of the information. The
31 screen and latex output is the content of the information. An InsetInfo can
32 have type "shortcuts", "shortcut", "lyxrc", "package", "textclass", "menu",
33 or "buffer". Arguments and outputs vary by type.
35 shortcuts: argument of this type of InsetInfo is the name of the LFUN such as
36 "math-insert \alpha". The syntax is the same as what is used in the bind
37 and ui files. The output of this inset is all shortcuts for this LFUN
40 shortcut: the same as shortcuts, but only output the last shortcut.
42 lyxrc: argument is the name of the rc entry such as "bind_file". Look in
43 src/LyXRC.h for available entries. The output is the content of this RC
46 package: argument is the name of a latex package such as "listings". The
47 output is "yes" or "no", indicating the availability of this package.
49 textclass: argument is the name a textclass such as "article". The output is
50 "yes" or "no", indicating the availability of this textclass.
52 menu: argument is the name of the LFUN such as "paste". The syntax is the same
53 as what is used in the bind and ui files. The output is the menu item that
54 triggers this LFUN. For example, "File > Paste", where '>' is actually
55 \lyxarrow (an InsetSpecialChar).
57 icon: argument is the name of the LFUN such as "paste". The syntax is the same
58 as what is used in the bind and ui files. The output is the icon use in
59 the toolbar for this LFUN. Alternatively, argument can be the icon path
60 without extension specified with respect to the images directory.
62 buffer: argument can be one of "name", "path", "class". This inset output the
63 filename, path, and textclass of this buffer.
65 lyxinfo: argument must (presently) be "version". This inset outputs information
66 about the version of LyX currently in use.
68 There is currently no GUI, no menu entry for this inset. A user can define a
69 shortcut for "info-insert" (e.g. C-S-I), and
71 1. input the type and argument of this inset, e.g. "menu paste", in
73 2. select the text and run "info-insert" (e.g. press C-S-I).
75 An alternative method is to enter command "info-insert type arg" in
76 the command buffer (view->Toolbar->Command Buffer).
