how to answer yes or no automatically in emacs

Question

I binded function semantic-symref to key C-c C-r like this:

(global-set-key (kbd \"C-c C-r\") \'semantic-symref)

everytime I pressed

Answer 1

You can advice semantic-symref with something like :

(defadvice semantic-symref (around stfu activate)
      (flet ((yes-or-no-p (&rest args) t)
             (y-or-n-p (&rest args) t))
        ad-do-it))

Beware that you're locally bypassing all confirmations, so you may catch further (other) questions triggered by semantic-symref itself.
