+\begin_layout Standard
+The purpose of a

+\family default
+ is obvious: it contains anything additional you might want to say about

+\family default
+.
+ It could also be used as a sheet of reminders for a particular

+.
+ In the case of the latter, you might want to make use of time markers.

+
+native
+\begin_inset Quotes erd
+\end_inset

+ support for time markers, a

+ So, you'll have to resort to using the LaTeX codes.
+\end_layout
+
+\begin_layout Standard
+To use time markers, you'll need to specify the extra class option
+\begin_inset Quotes eld
+\end_inset
+
+
+\family typewriter
+clock
+\family default
+
+\begin_inset Quotes erd
+\end_inset
+
+ [see section

+\end_inset

+\begin_inset CommandInset ref

+
+\end_inset
+
+].
+ This option turns on timing marks, which will appear in the lower-left-hand
+ corner of every
+\family sans
+Note
+\family default
+ you generate.
+ To set what appears in the time marker, you use the LaTeX commands
+\begin_inset Quotes eld

+
+\family typewriter
+

+\family default
+
+\begin_inset Quotes erd

+
+
+\family typewriter

+ The arguments of both commands are time measured in seconds.

+There's one last feature to describe.
+ Clearly, you'd like to print out all of your
+\family sans
+Slide
+\family default
+s and
+\family sans
+Overlay
+\family default
+s on transparencies while printing all of your
+\family sans
+Note
+\family default
+s on plain paper.
+ However, a
+\family sans
+Note
+\family default
+
+\emph on
+must
+\emph default
+ follow the
+\family sans
+Slide
+\family default
+ with which it is associated.
+ What's a person to do?
+\end_layout
+
+\begin_layout Standard
+Luckily, there are two LaTeX commands that allow you to select what to print
+ out.
+ Both must be placed into the preamble of your document.
+ The command
+\begin_inset Quotes eld
+\end_inset
+
+
+\family typewriter
+
+\backslash
+onlyslides{
+\backslash
+slides}
+\family default
+
+\begin_inset Quotes erd
+\end_inset
+
+ will cause the output to contain only the
+\family sans
+Slide
+\family default
+s and
+\family sans
+Overlay
+\family default
+s.
+ Correspondingly, the command
+\begin_inset Quotes eld
+\end_inset
+
+
+\family typewriter
+
+\backslash
+onlynotes{
+\backslash
+notes}
+\family default
+
+\begin_inset Quotes erd
+\end_inset
+
+ prevents the output of anything but
+\family sans
+Note
+\family default
+s.
+ I'd advise placing both commands in the preamble and initially comment
+ both out.
+ You can then preview your entire presentation as you write.
+ When you're done writing, you can then uncomment one of the two to select
+ what you want to print.
+ I like to uncomment
