the F1 key; the other is between the F8 and F9 keys. The user can release the
latches by pulling them toward the front of the computer. There is also a
keyboard locking screw, which is accessible from the back of the computer,
above the reset button next to the RJ-11 connector. Turning the screw five or six
turns counter-clockwise unlocks the keyboard.
Like the previous PowerBook G3 Series computers, the PowerBook G3 has a
key combination for resetting the computer: Ctrl-Command-Power. There is
also a reset button on the back of the computer.
Changing the Operation of the Keyboard 3
Several of the keys on the keyboard have more than one mode of operation. The
function keys can also control the display and speakers; the keys on the right
side of the keyboard can also be used as a numeric keypad; and certain control
keys can also be used as page-control keys. These changes are controlled by the
Fn key, the Num Lock key, and the Function Keys checkbox in the Keyboard
control panel.
The actual appearance of the keyboard is shown in Figure 3-4. The keys that
have alternate modes of operation are shown in Figure 3-5 and Figure 3-6.
Figure 3-5 and Figure 3-6 include duplicate versions of some keys in order to
show their alternate functions. In many cases, the alternate captions shown on
the duplicate keys do not appear on the keyboard.
