+A math macro is transformed internally to a
+\series bold
+
+\backslash
+newcommand
+\series default
+ command when exporting the document.
+ The created
+\series bold
+
+\backslash

+\series default
+ command is not placed in the LaTeX-preamble, therefore macros can only
+ be used in formulas that are in the document below the macro definition
+ box.
+\end_layout
+
+\begin_layout Standard
+Math macros can also be directly be created from a
+\series bold
+
+\backslash

+\series default
+ command.
+ When writing for example the command
+\series bold
+
+\begin_inset Newline newline
+\end_inset
+
+
+\backslash
+newcommand{
+\backslash
+larrow}[2]{
+\backslash
+xleftarrow[#2]{#1}}
+\begin_inset Newline newline
+\end_inset
+
+
+\series default
+in LyX as normal text, highlighting it completely and using then the shortcut
+
+\family sans
+Ctrl-m
+\family default
+, the command will be transformed to a math macro.
+ Using this method you need to be careful that the
+\series bold
+
+\backslash
+newcommand
+\series default
+ command is typed correctly, otherwise you get a faulty macro leading to
+ LaTeX errors.
+\end_layout
+
+\begin_layout Standard
+Math macros currently yet have the problem that further formulas in macro
+ definitions are handled wrongly.
+ Therefore the example
+\series bold
+
+\backslash
+fb
+\series default
+ from
+\begin_inset CommandInset ref
+LatexCommand ref
