Keyboard Controls and Programmable Function Keys
You can quickly adjust settings such as volume and screen brightness and eject a CD or DVD
disc using the keyboard controls.
Your PowerBook also has five additional keys that you can set up to open your frequently used
applications or documents. These keys are known as programmable (or hot) function keys.
For example, you can use these keys to open your Web browser, word processor, or favorite
game. Once applications are open, you can use the keys to switch quickly between them.
Assigning Programmable Function Keys
The first time you press one of the function keys, a dialog box appears that lets you assign
any of the function keys to an application. After that, you can change function key
assignments using the Keyboard control panel.
Using the Standard Function Keys
You can quickly change a key from a control or programmable function key to a standard
function key by pressing the Fn key while you press the other key. You can also use the
Keyboard control panel to reverse the keys so that the standard function keys are primary
and the screen controls and programmable function keys are secondary. (You would hold
down the Fn key to change the screen brightness, for example.)
