I think there needs to be a way to physically see what each key and key switch is mapped to. To see what characters correspond with each key. A guide and app and website isn’t good enough.
I was thinking of some type of screen or display technology to display what the mapping layout currently is programmed to. That could also dynamically change when a key or key switch is remapped.
My first idea is a laser projection display like a virtual keyboard. But it displays the Charachorder mapping layout on each half of the charachorder. I was thinking there could be a flat pull out or slide out tray in case there is not enough surface area to display the projection in the area around around the Charachorder.
My second idea is a small rectangular reference screen that can be either attached or sitting near the charachorder again see the mapping of the charachorder.
I will post images of what I am basing these two ideas off of.
