Multiple Screens?


I have 2 screens (monitors) here, the second on the right side is a extension of the first one - but the second monitor is switched off most of the time. Sometimes, if I start an application, it goes to the right (switched off) screen.
Would it be possible to move all the windows from all the screens to screen nr 1? Actually, the second screen is a projector, and I don't want to switch the thing everytime on to move the windows to the left screen. - I know it works also with keyboard shortcuts but a software would be better :)
