Marco Aurelio Valtas Cunha writes:

	I'm using the latex-suite to write in Portuguese. Portuguese often has
	caracters like 'ã' but latex-suite maps this to \cite{}. After look
	around I couldn't find a simple way to 1) remap or 2) disable.

Solution:
Provide new globally visible functions Tex_MathBF, Tex_MathCal and
Tex_LeftRight. Use mapcheck() to check whether a map exists for these
functions before mapping the alt keys to trigger them. This enables people
who might need the alt keys for other uses to utilize this behavior and
keep the original behavior of their alt keys.

Example:
In order to use some other key, (say <CTRL-c>) to use Tex_MathCal(), do the
following

	inoremap <buffer> <silent> <C-c> <C-r>=Tex_MathCal()<CR>

If you do not want to use this functionality at all, do something like:

	inoremap <buffer> <silent> <plug>1 <C-r>=Tex_MathCal()<CR>

This will never trigger the map.

  " Desciption:
+ " 	This ftplugin provides the following maps:
+ " . <M-b> encloses the previous character in \mathbf{}
+ " . <M-c> is polymorphic as follows:
+ "     Insert mode:
+ "     1. If the previous character is a letter or number, then capitalize it and
+ "        enclose it in \mathcal{}
+ "     2. otherwise insert \cite{}
+ "     Visual Mode:
+ "     1. Enclose selection in \mathcal{}
+ " . <M-l> is also polymorphic as follows:
+ "     If the character before typing <M-l> is one of '([{|<q', then do the
+ "     following:
+ "       1. (<M-l>       \left(\right
+ "               similarly for [, |
+ "          {<M-l>       \left\{\right\}
+ "       2. <<M-l>       \langle\rangle
+ "       3. q<M-l>       \lefteqn{}
+ "     otherwise insert  \label{}
+ " 
+ " These functions make it extremeley easy to do all the \left \right stuff in
+ " latex.
+ "
+ " NOTE: The insert mode maps are created only if maps are no maps already to
+ " the relevant functions Tex_MathBF, Tex_MathCal and Tex_LeftRight. This is to
+ " enable people who might need the alt keys for typing to use some other
+ " keypress to trigger the same behavior. In order to use some other key, (say
+ " <C-c>) to use Tex_MathCal(), do the following
+ "
+ " 	inoremap <buffer> <silent> <C-c> <C-r>=Tex_MathCal()<CR>
