Add option to disable default keybinds

I often find myself typing into a previously sent message (editing it) because I've pressed the up arrow. I cannot disable this because it is impossible to turn off default keybinds (like this one). Keybinds generally make things easier and quicker; however, this "up arrow" thing is a frequent frustration for me. I suspect that others may have experienced a similar problem, perhaps with another keybind. I think this could be easily solved by providing an option to disable default keybinds. Thank you for considering my suggestion.
