This is an infuriating problem with probably a simple solution, but I’m new to CE. I’m also a windows guy, I mean I can type commands into a terminal, but I don’t have any linux machines set up right now, hopefully don’t need to. Anyway, the problem is that cursed backslash key that toggles fullscreen. It is impossible to disable in CoreELEC using any method I can think of. In Leia, the keyboard.xml file in /usr/share/kodi/system/keymaps/ sets it, and nothing on any other accessable part of the system will change that. Try it; put a custom keymap in /userdata/keymaps, and nothing you do will disable that bloody backslash key. I tried using keymap editor in Kodi to change it, no dice, I know now it’s because of the RO file in the kodi system folder.
tl,dr; I need to edit the keyboard.xml file in /usr/share/kodi/keymaps to comment out the backslash/fullscreen toggle line. I can’t find any way to do that other than ssh, which I will do, but only if there’s no other way. Help me please, I love CoreELEC so far (it turned my buggy, bloated TX92 into an awesome 4K Kodi box) but every time I accidentally hit that backslash and it knocks it into 1080… (if you use a KB with Kodi, you must know what I mean)
