+A math macro is transformed internally to a

+
+\backslash
+newcommand
+\series default
+ command when exporting the document.
+ The created
+\series bold

+in LyX as normal text, highlighting it completely and using then the shortcut

+, the command will be transformed to a math macro.
+ Using this method you need to be careful that the
+\series bold

+\backslash

+\series default
+ command is typed correctly, otherwise you get a faulty macro leading to
+ LaTeX errors.
+\end_layout

+\begin_layout Standard
