GtkComboBox popup

[Erich Hoover <ehoover mines edu>]

I'm currently handling all the keystroke events that come to my 
application (using key_press_event and key_release_event) and have 
'hotkeyed' a GtkComboBox so that when the user presses F2 the combo box 
will expand it's popup window.  I would also like the user to be able to 
press F2 to close the popup (if it is already open) but the popup seems 
to take complete control over the keyboard so my application no-longer 
processes any keyboard events.  Any help is greatly appreciated.
