Another good one on that level was using the Windows keyboard shortcut ctrl-alt-down to rotate the display upside down - totally harmless, but absolutely maddening if you don’t know how to undo it

Even better if you combined it with an upside down screenshot of the desktop. So it looked like only the mouse was upside down and all buttons didn't work.

I think it's a good thing that Ctrl+Alt+Arrow is no longer intercepted by graphics drivers, since IMO shortcuts not containing Win should be handled by apps and not the system.
