I originally thought about going this way, but realize it was not the
right way: KToggleAction represents a *checkable* action, so it will
always stay down when clicked. There is no way, as far as I can tell, to
fix KToggleAction so that one can set an alternative KGuiItem for its
checked state without making it checkable.
