I would like to have on-screen hunt and peck support to help learn the original or custom keymaps.
I expect that it means that “raw” key up/key down events need to be transmitted to system without regard to any mode or shift state. “raw” here means that the textblade has done all of it’s decoding of real-world finger sensing to keystroke but not mapping to shift state or anything else, just key codes.
This “raw” map is interpreted by the system and allows display of a graphical version of the textblade and lines connecting to other key maps/graphical versions that represent different shift states. The lines are labeled with the shift sequence needed to bring the shift-mappings to the foreground.
I might be happy just being able to print a chart laid out in this manner.
That reminds me of a years old request of mine; I’d like to be able to export and import human readable keymaps that I can process myself.
