alt + mouse drag - life saver

So you guys probably know this, but I just found this out today.
If you get a gnome control panel or program preferences panel that comes up that does not fit on the screen and you cannot see the control buttons because they are of the bottom of the screen, you can hold the alt key down then drag the panel up the screen, holding down the left mouse button, you can get to the hidden buttons.
gdmsetup is a good example.
