The Ctrl-Alt-Direction key sequence is supposed to be used for changing your workspace. On my computer at work it changes the screen orientation.
Ctrl-Alt-Up - right side up
Ctrl-Alt-Right - 90 degrees
Ctrl-Alt-Down - 180 degrees
Ctrl-Alt-Left - 270 degrees(If that doesn’t work, try Ctrl-Shift-R)
This is a feature in Windows XP Tablet PC Edition. Which makes sense. But it looks like ATI Intel copied the keystroke for the same “feature” in their video card drivers. I can’t think of a good reason why I would need an always-on keystroke for this on a desktop PC.
