focuse binding

[Jiang XU <jiang xu echostar com>]

I want to use the arrow keys as a control in my application, but GTK+
keeps stealing the key press events to move the focus around.   So, I
try to break those default bindings, so that the arrowkey won't move
focus around.

But I don't know how to break those default bindings, Any one can Help
me????  I really appreciate that
