Switching the Functions of Keypad Keys

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

The embedded numeric keypad cannot be used while an
optional external numeric keypad is connected to the notebook.
Most keys on most external numeric keypads function differently
depending on whether num lock mode is on or 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
the arrow, page up, or page down keys.
