10-key keypad on laptop

I ask for the same thing years ago.

For me that use lots of number it isn't practical inserting a bunch of numbers using the "letter keypad" .

The answer that i got was "buy a numeric keypad with USB or Bluetooth".

While we are on the subject:

¿does anyone have a straightforward procedure for enabling the numerics in the ... JKL... keys on the keyboard, as if it were an imbedded numeric keypad?

Last time I went looking, I could not find a simple way.
