Hi,

I found this custom command at http://www.crsr.net/Notes/Emacs.html :

;;; Use "%" to jump to the matching parenthesis.
(defun goto-match-paren (arg)
  "Go to the matching parenthesis if on parenthesis, otherwise insert
the character typed."
  (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))) ))
(global-set-key "%" 'goto-match-paren)



I am trying to change the global-set-key to something like "\C-.", but this
isn't an acceptable 'string and I don't know why.  Can anyone help?

regards,
Rich

Control-period is not an ASCII character, so it cannot be included in a
string.  But it can be included in a vector: [?\C-.]  See the "String
Basics" node of the Emacs Lisp manual.

Ooh, nice!  That works.  I'll have a look at the manual next time I try
something like that, didn't even kow about vectors (don't really know
anything about lisp, on that matter).

cheers,
rich

This works here:
(global-set-key (kbd "C-.") 'goto-match-paren)
