Right, but we can't re-create the menu while it's in use, so either the
entry has/is a submenu or it isn't.  It doesn't offer "some mouse
gesture" for the user to select "the entry that corresponds to
a submenu".  AFAIK the only thing you can do is walk the tree for
a while and at the end select one of the leaves.
