Number Pad - Home Position

Like the character keys on the main keyboard, there is also a
Home position and fingering positions for the number keypad.
In this case, the
Home key is the number
5 key (which also has a raised dimple on it).
This key would correspond to your middle finger (
R3).
So the Home row for the number pad are:
4, 5, 6 corresponding to fingers
R2, R3, R4.
The little finger (
R5) would control the
Enter/Return key and the thumb (
R1) would be positioned over the
0 key.
NOTE: If you have a left-handed keyboard where the the number keypad is on the left, then the finger positions would be reversed with the key sequences remaining the same.
As the numbers are laid out in straight columns, the movements of the fingers are now more intuitive.
- The Thumb (R1) types the 0 key
- The Index finger (R2) types key 1 4 7
- The Middle finger (R3) types key 2 5 8 / [*]
- The Fourth finger (R4) types key . 3 6 9 [* - +]
- The Little finger (R5) types the Enter/Return
Finally, what we are left with are the Operator keys (/ * - +).
If we follow the same pattern, then the middle finger (R3) should control the divide key (/) and the fourth finger controls the others (* - +).
But some people prefer to use the Middle finger to control the multiply key (*) as it's easier to reach with that finger.
At this point, i would just say, go with what you feel more comfortable and easier to use!
