What buttons forward via CEC is almost entirely dependent on the TV and is usually a relatively small number. The only exception would be that a TV might allow more or less buttons to be forwarded depending on what CEC device type it sees connected. OSMC (Kodi? not sure) by default identifies as recorder 1. If your really curious search my posts and in the last couple weeks this was brought up for someone that needed to set their unit as player 1 in order for their particular TV to work correctly. I doubt that this path would lead to different result outside of a rare exception, but feel free to try changing it yourself and see if it gets you anywhere.
This means that it is recognizing the button but it is globally mapped to something that Kodi is giving preference to so it tries executing whatever that is instead of letting the add-on map it. One way Iāve found to get around this is by putting the following keymap in and loading it via the terminal. It breaks navigation so once you got the info you needed you just pull it back out and reloadkeymaps againā¦
