Possible to remap `Esc` key to `Caps Lock` on a bluetooth keyboard
In Android 4.0 you could do this easy, you would need root permissions though. You most likely still can with root. Just checked can do easy with root. /System/usr/keylayout there are a couple files in there with keyboard layouts that you can edit with root permission. You can veiw but not edit in fx file manager, there are other files that control the same types of things in there.
