It's  automatic. When  you  close a  paren,  the cursor  moves to  the
matching  opening paren.   Or, if  you double-click  on one  paren, it
selects all  its contents and  the matching paren  too. Or if  you use
backward-sexp or forward-sexp (C-c , or C-c .), it moves over matching
paren.

I don't  think modes can be  defined locally.  In these  cases, I just
change the major mode.  It may help to use narrow-region and widen.
