I use wireless numpad and wireless trackball to control Kodi, but unlike VLC, it seems difficult to assign buttons/keys to concrete functions.
For example, I’ve tried to create a file as ~/.kodi/userdata/keymaps/mouse.xml with this content (replace “[” by “<”) with no effect:
[keymap]
[FullscreenVideo]
[mouse]
[wheelup]VolumeUp[/wheelup]
[wheeldown]VolumeDown[/wheeldown]
[/mouse]
[/FullscreenVideo]
[/keymap]
Where can I find solid documentation about this?
