BTW, a good strategy to find out what happens after hitting some key is
to use C-c k to see which command will be invoked, and then to M-x
debug-on-entry this command.  I do that so often that I wrote an own
command doing that, and bound it to a simple key:

(defun my-debug-on-next-key ()
  "Enter the debugger for the next command."
  (interactive)
  (let* ((keys (read-key-sequence "Debugging next key sequence..."))
         (cmd (key-binding keys)))
    (debug-on-entry cmd)
    (unwind-protect
         (call-interactively cmd keys)
      (cancel-debug-on-entry cmd))))
