Glossary » command key
or Apple key; a key on the Macintosh used as a shortcut to issue commands, by holding down the command key and pressing another letter. The command key is usually labeled with a small cloverleaf symbol on the Macintosh. The commands are typically items in menus that are marked with the cloverleaf symbol and the associated key.
