Types
-
On Apple keyboards, the command key may be designated with the word "Command," an Apple computer logo or a Gorgon loop (?) printed on the key. The designation varies based on the age of the keyboard. MacBooks include both the "Command" and "?" designations.
Effects
-
Pressing the command key alone as no impact in Mac OS X. It must be used in tandem with other keys. For example, in most applications, pressing "Command" and "Q" simultaneously closes all open windows and quits the program. On MacBook models, there are two command keys, located on the left and right sides of the space bar.

Fun Fact
-
In the event a non-Apple keyboard is used, as may be the case when connecting the MacBook to an external monitor while in closed clamshell mode, the command key is mapped to other keys. For example, when a Windows-compatible keyboard is connected to the MacBook via Bluetooth or USB, the Windows key functions as the command key.
