I don't know if others will find this useful. I made the following keybinding changes:
1. `W` key reassigned to `E` to make `WASD` free of conflicts.
1. Directional keys mapped to `WASD`
1. Additional `ok` and `cancel` buttons assigned to `F` and `C`.
1. A new function - Toggle Control - introduced. The `F1` key will toggle between Control being held down and not. Either `F1` or Control will reset this function. Primary use of this is to "hold down control while the window is not in focus" - i.e. do other stuff while skipping content.
