Command key

The Command key, also historically known as the Apple key, open-Apple key, "command squiggle", waffle key or meta key, is a modifier key present on Apple Keyboards. The Command key's purpose is to allow the user to enter keyboard shortcut commands to GUI applications. An "extended" Macintosh keyboard—the most common type—has two command keys, one on each side of the space bar; some compact keyboards have one only on the left.
