Whenever I click Alt + Arrow up/Arrow down my screen will do an unwanted flip. I'd like to disable this shortcut behaviour. I've already looked at Super User question How to stop my laptop's screen from rotating when I press Alt + Arrow?.
But Ctrl + Alt + F12 doesn't start any menu for me. How can I fix this problem?
I have an Nvidia graphic card, 2100M, and Windows 7 on a Toshiba computer.
