Pointing Devices and Keyboard 3–3
Switching key functions on the embedded
numeric keypad
You can temporarily alternate the functions of keys on the
embedded numeric keypad between their standard keyboard
functions and their keypad functions by using the
fn key or the
fn+shift key combination.
■ To change the function of a keypad key to keypad functions
while the keypad is off, press and hold the
fn key while
pressing the keypad key.
■ To use the keypad keys temporarily as standard keys while
the keypad is on:
❏ Press and hold the fn key to type in lowercase.
❏ Press and hold fn+shift to type in uppercase.
Using an external numeric keypad
Most keys on most external keypads function differently
according to whether num lock mode is on or off. (By default
num lock mode is off.) For example:
■ When num lock is on, most keypad keys type numbers.
■ When num lock is off, most keypad keys function like the
arrow, page up, or page down keys.
When num lock on an external keypad is turned on, the num lock
light on the computer is turned on. When num lock on an external
keypad is turned off, the num lock light on the computer is
turned off.
If the external keypad is connected, the embedded numeric
keypad cannot be turned on.
