Let's say I want to create a "macro" called
\limx that will be defined as:
How can I make LyX recognize it and make an auto-prieview of it?
Another example, I'm using the cancel package. When I'm using
\cancel in a math equation it doesn't preview it while editing. I can still see "
\cancel" on the equation editor. Only when I render the document the
\cancel is being really rendered. How can I add that functionality to the LyX's WYSIWYG environment as well?
