Unable to rebind any or most keys.

[JTKaay]

Im not sure if it is VA or HCS relevant, but as HCS uses Custom Binds, I am in need of some help. Perhaps someone can help.
I wanted to rebind my flying keys (for Anti Thargoid stuff) to mouse. I change all the needed or wanted keybinds, press Apply. Nothing changes. When I come back into to more settings, all the settings I made directly beforehand are gone.

What am I doing wrong?

hi, use ingame (elite option) the left side for your keybinds mouse/controller, and use the right side for VA/hcs only and you need all keys to bind to hcs . and there is a difference betreewn horizion. and oddi. so odd use 4 ship srv foot and all. hori has only 3. when u change from oddi. to horiion the keys will not work.

va/ hcs read your keybinds from the game. first change keybinds then save, then start Va/hcs
