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 an external keypad is connected, the embedded numeric keypad cannot be turned on.
Enabling or disabling num lock mode as you work
To turn num lock on or off on an external keypad as you work, press the num lk key on the external
keypad, not on the computer.
