function def && eval exp.

function def && eval exp.

[Baloff]

Hello

using the shell in emacs
$ls -l
-rw-r--r--  1 sam sam    319 Jul 31 13:00 ^[[0mmain.cpp^[[0m
to remove those strange character around the filename I

M-: (ansi-color-apply-on-region (point-min) (point-max))

I have currently in my .emacs this function which removes 

all the ^M from text which get infested with it.
(global-set-key [f5]      'cut-ctrlM)	; cut all ^M.
(defun cut-ctrlM ()  
  "Cut all visible ^M."
  (interactive)
  (beginning-of-buffer)
  (while (search-forward "\r" nil t)
    (replace-match "" nil t))
  )

how can I do both, eval the expression and run the function by the [f5]key.

thanks
