Sun Microsystems keyboard with a Meta key

The Meta key was a special key on old MIT computer keyboards, such as the Space-cadet keyboard. Sun keyboards continue to include a Meta key, marked as a solid diamond.

The key may be considered equivalent to the Macintosh's command key, which has the same location and similar function. On modern keyboards, it is usually emulated with Alt key or with the Windows key. As an alternative in some programs, Meta key is emulated by pressing and releasing the Esc key (see Emacs FTW).

The Compose key is sometimes known as a "meta key".
