No, you are right. I have modified d.zoom, because I hated to accept/reject
each selected region. 
We could add "previous region", but we don't have enough buttons on mouse.
This problem appears on many places. 

Would it be possible to catch keystrokes by
R_get_location_with_pointer()? It would be also useful to have some
way, how to break running R_get_location_with_pointer() from GUI.
