By pressing "alt+tab" simultaneously on your keyboard (or Command-Tab on a Mac), you can hide the window that's on your screen and bring up one from behind it. This trick is used frequently by people in offices to hide the fact that they're surfing the Net instead of doing their work. You may hear, "I couldn't finish checking out that Flash site you told me about because my boss walked by and I had to alt-tab it."
