.. warning:: When used with MuMaMo (see `ein:notebook-modes'),
   keyboard macro which manipulates cell (add, remove, move,
   etc.) may start infinite loop (you need to stop it with
   ``C-g``).  Please be careful using this option if you are a
   heavy keyboard macro user.  Using keyboard macro for other
   commands is fine.

.. (Comment) I guess this infinite loop happens because the three
   modules (kmacro.el, mumamo.el and smartrep.el) touches to
   `unread-command-events' in somehow inconsistent ways."
