I have the following in .emacs:

(global-set-key "%" 'match-paren)
(defun match-paren (arg)
  "Go to the matching parenthesis if on parenthesis otherwise insert %."
  (interactive "p")
  (cond ((looking-at "\\s\(") (forward-list 1) (backward-char 1))
        ((looking-at "\\s\)") (forward-char 1) (backward-list 1))
        (t (self-insert-command (or arg 1)))))

When I press % over ( or ) I am going to the other paranthesis.
(This is slightly inconvenient if you must type   %(...) things often.)

Sincerely yours, Roman A.Suzi
