Hi Eli,

Aha! Thanks!
This works:

  (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)))

  (defun rd () (interactive) (redisplay 'force))
  (defun s () (interactive) (rd) (sleep-for 1) (rd))

  (defun eeks (str &rest rest)
    (eek str)
    (if rest (progn (s) (apply 'eeks rest))))

    (eeks "RET ab" "cd" "ef")

Cheers =),
