Alternatively referred to as the beanie key, cmd key, or open apple key or just command, the command key is a key created by Susan Kare that is found on all Apple Macintosh computer keyboards between the alt or option key and the space bar key. This key enables a user to perform tasks by pressing it in conjunction with one or more other keys. The picture is an example of what this key looks like on the Apple keyboard.
Tip: Users that are not familiar with the Apple Macintosh, but are familiar with IBM compatible computers can relate this key to the Microsoft Windows key. If you have a Windows keyboard on an Apple keyboard, the Windows key becomes the command key.
