Sorry I missed it in that first link you provided but
Turns out to be right in the emacs FAQ.   I repost it here incase
people searching these forms should hit this thread.

I didn't really like the idea of turning on a whole vi like mode and I
guess a good number of others didn't either.

   * Here is some Emacs Lisp that will make the <%> key show the
     matching parenthesis, like in `vi'.  In addition, if the cursor
     isn't over a parenthesis, it simply inserts a % like normal.

          ;; By an unknown contributor

          (global-set-key "%" 'match-paren)

          (defun match-paren (arg)
            "Go to the matching paren if on a paren; 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)))))
