Another option is to add a keyboard accelerator ... this is the mechanism GTK
uses for the <ctrl>Q or whatever keyboard menu shortcuts. Unfortunately it's
rather (ahem) weakly documented, as far as I know.

An easy hack is to make an invisible menu item with your key combination as a
shortcut, and connect to "activate" on the menu item. You won't get an (x, y)
position though (did you want that?).
