Hi

Looks like media keys (play / stop / next ...) are not supported yet.

Please please please add them :D

Is there any workaround in the meantime to add media keys?

In the keymap.rb file, I tried to just add the decimal number for MediaPlayPause (179) instead of a named keycode, but it crashed.
https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.keys?view=windowsdesktop-6.0

kbd.add_layer :default, %i[ KC_ESC KC_1 KC_2 179 KC_4 ... ]

Thank you very much!

Thanks for the request.
Unfortunately, simply sending a media keycode won't work.
We need to implement a low-level HID feature so that media keys work.
I definitely have the plan to do that. Be patient!!!
