Re: From macros to elisp programming?

[Eduardo Ochs <eduardoochs@gmail.com>]

Hi Ypo!

You may find this useful too. I often use it when I want to put
editing commands in my functions and I'm in a hurry and not in a mood
to find their names - so for example I use (eek "C-l") instead of
(recenter-top-bottom), or (eek "<up> C-a C-SPC <down> M-w C-y") to
duplicate the line above the point...

  Cheers & happy hacking =),

(defun eek (str)
  "Execute STR as a keyboard macro. See `edmacro-mode' for the exact format.\n
An example: (eek \"C-x 4 C-h\")"
  (interactive "sKeys: ")
  (execute-kbd-macro (read-kbd-macro str)))
