switching screens

[bibarnes]

I was wondering if there was a keyboard key combo to be able to switch cursor from one screen to another. If I am playing a game on my main screen and something neds attention on the other I can't move the cursor off the game

I think that at the time of 2 monitors touching together, then they will allow the cursor to move between the screens properly.
