+Both paragraph styles and inset layouts allow for
+\emph on
+arguments
+\emph default
+ as well as the main content.
+ This is especially useful for things like section headings and only makes
+ sense with \SpecialChar LaTeX
+.
+ Each (optional or required) argument of a command or environment—except
+ for the required argument that is associated with the content—has a separate
+ definition, where the number specifies the order of the arguments.
+ The definition must end with
+\begin_inset Flex Code
+status collapsed
+
+\begin_layout Plain Layout
+
+\change_inserted -584632292 1615846730
+EndArgument
+\change_unchanged
+
+\end_layout
+
+\end_inset
+
+.
+ So a command with two optional arguments looks like:
+\end_layout
+
