Paired delimiters

Paired delimiters

[Uday S Reddy]

The Elisp manual says that the "paired delimiter" syntax class is "like 
string quote characters except that the syntactic properties of the 
characters between the delimiters are not suppressed".  But the 
description of the string syntax class doesn't talk about "suppressing" 
anything.  So, I am at a loss to understand what the difference is 
between the string class and paired delimiter class.

The context of my query is that I am trying to get the autopair-mode

  http://code.google.com/p/autopair/

to correctly in LaTeX-mode.

Cheers,
Uday

It's not very well defined, really.  Basically it means things like:

       "{" is perfectly valid
whereas
       ${$ is ill-balanced

and

       "foo % this is not a comment"
whereas
       $foo % this is a comment and this $ does not match the other.

FWIW you may also like to take a look at electric-pair-mode (new in
Emacs-24).
