 I don't believe the user can take any such action. Once the control has
focus it always keeps it on some item. In fact, AFAIK the only case when
there can be no focus at all is when the control is empty.

 I think it would be more logical. If the control supports multiple
selections, all actions should normally be applied to all the selected
items, not just to the focused one.

 What would be the advantage of doing this? Or, alternatively, what is the
problem with using wxListCtrl?
