The keyboard with a 5.9 feet long cable and Mac layout scores with 13 special functions arranged on the F-keys such as Mission Control, Spotlight Search, screen brightness, Lock PC and media control. They are executed directly. To access the default functions on the F-keys, hold down the FN key and select the appropriate key. If you want to run the standard functions permanently, press the Control and FN keys at the same time. The FN LED in the F14 key lights up when the FN key is locked.
