+Sometimes,
+ you may need to use a LaTeX package which defines a math command that is not
natively supported in LyX.
+ This is easy enough to do:
+ Just include the package in the preamble and type out the command in math.
+ As with commands defined in the preamble,
+ however,
+ the display in LyX will not be `nice'.

+As of LyX 2.4,
+ this problem has been solved.
+ Just define a math macro with empty LaTeX slot!
+ The LyX part will be used for display,
+ but no corresponding LaTeX will be output.
+ For example,
+ the

+ package defines a Godelnum macro that puts a single argument into corner
quotes.
+ To get a nice LyX display of this macro,
+ just do:
