jumping to peer parenthesis/brace

[Pawel]

Hallo group members

Could You tell me ow to do the following thing:

{<------ my pointer is here and I want to jump there
.....                                           |
...[.......]                                    |
}<-----------------------------------------------

highlight-paren-mode is not enough when block is larger than screen

Greetings

What is the difference between C-M-n (forward-list) and C-M-f (forward-sexp) ?

For/Backward-sexp works always. A "sexp" is a "balanced expression."  
I do not understand this concept completely, but as examples I've  
seen it work over {} and [] and () balanced blocks, as long as the  
point is at the block but outside of it. If there is none such, the  
sexp is a word, because it's "balanced" by white space or  
punctuation? In any case some movement happens.

For/Backward-list moves over the block *plus* the characters between  
the point and the end or beginning of the block. When inside a block,  
it produces an error, at least in TeX code -- which I really do not  
like.

Somewhere I picked `match-paren': it allows you to jump to and fro
without changing the key:

(defun match-paren (arg)
  "Go to the matching parenthesis if on parenthesis otherwise insert %."
  (interactive "p")
  (cond ((looking-at "\\s\(")
         (forward-list 1)
         (if (eq 0 (string-match "XEmacs" (version)))
             (backward-char 1)
           (when (eq 41 (char-before))
             (backward-char 1))))
        ((looking-at "\\s\)")
         (forward-char 1) (backward-list 1))
        (t (self-insert-command (or arg 1)))))

with

(global-set-key "%" 'match-paren)
or better
(define-key emacs-lisp-mode-map "%" 'match-paren)

Attention: If editing format strings, it might happen you are
over a `(' while inserting a `%' is in your mind. That's an
occasion, `match-paren' will not DTRT.

So choose an other key to call match-paren eventually.

PS.: Posting this I see, `match-paren' could do better by handling
brackets and braces also. Maybe someone will enhance it after
reading this? Maybe in paredit.el is the enhancment already?

In that case, you can quote the `%':
  C-q %
to insert it.
