numeric keypad / Map the “Comma” key to “Period”

[Didier3L]

Good morning,

I have a Logitech Mx Keys keyboard which has a numeric keypad.
I can't map the "comma" key on the number pad to "Period"

there are two solutions to do this:
1, Press the "shift" and "comma" keys on the numeric keypad at the same time to obtain a "Point"
2, Press the “shift” and “semicolon” keys on the keyboard at the same time

Can you help me ?
