Thanks for the explanations.
I'm just interested in these keys:
Pause / play, stop, back, rewind, forward, ok, power, and directional arrows.
On kodi (on windows 10) I installed the Keymap Editor Addon but it does not work.
A remote control with the keys already mapped I think it does not exist.
I've seen the advice of the Xiaomi Mi Box Bluetooth, but it has a few buttons.
