I also love customizations and setting up my own keybinds for my preferred ergonomics. So naturally, I was looking for this answer in the past too, but I changed my mind after a while. Think it like changing Windows keybinds. Usually games or apps don’t make menu navigation customizable and even in instances that it’s possible, I recommend not doing it since it might cause issues in the future. Maybe a new update will come out and they won’t think about adjusting certain things for users like you, which may result in conflicts.
To answer your question though, there are many customizable settings under editor peferences. Changing shortcuts will definetly not cause any issues now or in the future but I don’t know if what you want is one of them. See if it’s there!
