Numeric Keypad Mode
The mode in which some of the character keys are used as numeric keys (with a key layout that
makes numeric input easier) instead of their normal functions is called numeric keypad mode. The
keyboard is switched to numeric keypad mode with [Num Lk]. (In numeric keypad mode,
displayed on the status indicator LCD.) The keys surrounded by thick lines in the diagram above
become the numeric keypad. The numbers input with these keys are printed in pink on the front of
each key.
Critical Point
When the separately sold numeric keypad is connected, if you press Num Lk to put the computer
into numeric keypad mode, the keys on the external numeric keypad are enabled, but the
numeric keypad section on the keyboard is disabled.
