Whenever i click alt-arrow up/down my screen will do a unwanted flip. I'd like to dissable this shortcut behaviour. I've already looked at this link: How to stop my laptop's screen from rotating when I press ALT-ARROW?
But ctrl alt f12 don't start any menu for me. I'm having nvidia graphic card 2100m, windows 7 on a toshiba computer, any help is much appreciated.
