That looks complicated. Maybe I'll just stick to the cheap remote for now. Reading that thread it says kodi does not recognise the OK key and expects the enter key. That would seem like an odd omission in kodi not to responding to the OK key on a remote, rather than just treat it as the enter key by default.
The OK button works if I turn on the Air Mouse Function via a button on said remote, and stops when I turn Air mouse off via the same button. Therefore I am not fully convinced the remote is actually sending anything when I turn the Air Mouse off which would explain why I could not get the keymap editor to remap it.
Can anyone recommend a high quality 2.4G remote with dongle, with a keyboard on the rear ?
