Macintosh computers have a special command key marked by a four-leaf clover or an apple. The Command key is similar to a PC's
Alt key -- you hold it down while pressing another
key to
execute some operation. Typically, command-key combinations are shorthands for
menu choices. For example, on the
desktop, pressing the Command key and O is equivalent to
selecting the
open option from the
file menu.
The Command key is sometimes called the Apple key or Open Apple.
