Changing the Operation of the Keyboard

Several of the keys on the keyboard have more than one mode of operation.

• Function keys F1-F6 can also control the display brightness, speaker volume, and the Num Lock function.
• The other function keys can be set by the user to open applications, documents, or AppleScripts.
• Certain control keys can be used as page-control keys.
• The keys on the right side of the keyboard can be used as a numeric keypad.

The next sections describe these groups of keys and the way their alternate modes of operation are selected by using the Fn key, the Num Lock key, and the Function Keys checkbox in the Keyboard control panel.
