Why QWERTY keyboard structure

Why is the text input presented with a keyboard QWERTY structure. Is it possible to connect a QWERTY structured keyboard to it? Or even better is it possible to change this visual structure?

:melting_face: It now feels a bit silly with only the turning-selecting knob to find my way to and from the different functions (on the presented keyboard visualisation) like backspace, capslock and spacebar. I think regular tv-remote text input possibilities would be better manageable – first the main knobs like backspace, capslock, spacebar, etc and then simply a b c d e f etc.
