Switching Key Functions
You can temporarily switch the functions of an embedded
numeric keypad key between its standard function and its keypad
function.
■ To use a key on the keypad as a keypad key while the keypad
is turned off, press and hold
fn while pressing the key.
■ To use a key on the keypad as a standard key while the
keypad is turned on:
❏ Press and hold fn to type with the key in lowercase.
❏ Press and hold fn+shift to type with the key in uppercase.
Releasing
fn returns a keypad key to its set function. For example,
a keypad key returns to its keypad function if the keypad is turned
on or to its standard function if the keypad is turned off.
Using an External Numeric Keypad
✎
Depending on your configuration, the embedded keypad may
be unavailable while an external keypad is connected to the
notebook.
To turn num lock mode on or off on an external numeric keypad,
press the
num lk key on the external keypad, not on the notebook.
■ When an external numeric keypad is turned on and is in num
lock mode, the num lock light on the notebook is on.
■ When an external numeric keypad is turned off or is turned on
with num lock mode turned off, the num lock light on the
notebook is off.
Most keys on most external numeric keypads function differently
when num lock mode is on than when num lock mode is off. For
example:
■ When num lock mode is on, most keypad keys type numbers.
■ When num lock mode is off, most keypad keys function like
navigation keys.
