How to move an off-screen window back to your main monitor?

If you turn off or unplug a secondary monitor while XP is running and there's an application window that was displayed on the secondary monitor, you may wonder how to get it back to the main screen. Here's the secret:

1. Click the application in the taskbar to put the focus on it.
2. Right click it in the taskbar and select Move
3. Press the appropriate arrow key (Left or Right, depending on the direction in which you need to move the window to bring it back to the main monitor)
4. Move your mouse or pointing device in the same direction, until it moves back into view on the main monitor.
