The Command key is a key found on Apple keyboards that is used with a single letter key for many of the Macs most common actions, such as copy, paste, and print. It is located next to the Space bar on either side and is labelled with the quadruple loop symbol: ⌘. On a PC keyboard, the Command key is either the Windows key or the Start key. The Windows key is located to the left of the Space bar and has a Windows logo on it. The Command key is sometimes used like the Control key in Windows, but the Macs Option key is also used for Windows Control key functions. If you are using a Windows keyboard on a Mac, the following are the primary key substitutions on the Windows keyboard, and their Macintosh equivalents:

• Windows key = Command key
• Control key = Control key or Command key
• Alt key = Option key
• Delete key = Backspace key

In summary, the Command key on a Windows keyboard is either the Windows key or the Start key, located to the left of the Space bar.
