Anyone seen my lost buttons?

At some time in the recent past, I suspect after I have downloaded a new aircraft, I have managed to "mislay" the row of buttons that bring up GPS, Radio Shack etc from some, if not all of my default fs2002 aircraft. 
If anyone can tell me how to bring them back I would be gratefull. I know you can use the keyboard to activate these functions but the row of blank black squares is really beginning to get to me.
Many thanks in advance.
