In GTK+ keyboard events are recursively propagated from the hierarchy parent down to its children. Sometimes this is not what we want. E.g. The inputline is active, the user presses the 's' key, we want it to be sent to the inputline, but because the main menu is further up the hierarchy, it wins and the inputline never gets anything! This function ensures an entry widget (like the inputline) always gets first dibs at handling a keyboard event.
