gtk eating tab hotkey

[Dan McMahill <mcmahill mtl mit edu>]

I've created a main menubar with a handful of menus using the UI 
manager.  All of my hotkeys work except for the menuitem which uses 
"Tab" as the hotkey.  The problem is that gtk eats the tab and uses it 
to move the focus around my different buttons and and other widgets on 
the screen.  Then the menus never get triggered by a "Tab" press.

Is there a way to tell Gtk to not eat keys like Tab and <shift>Tab so 
that I can use them as hotkeys?  Or do I have to capture the keypress 
event and wire it back into the menus myself?  That seems like a pain!

Thanks
