Re: Conditional imap

I did what you told me to (i dont want to use "(<Tab>" but just "(" to remap
to "\left("). When I enter the command while i opended the Document
everything works fine. But when I put the command in my .vimrc (or the
tex.vim respectively) it stops working.

The map is present, it just won't replace the "(".

Any Idea?
