With a new firmware in the AG5 we don't talk about a single table lookup anymore. The development version will simply send a sent of scancodes that are processed in the host computer.
Autohotkey is then used to transform exactly these scancodes to regular keypresses. This autohotkey script has to know the scancode-to-AG5-key mapping in order to perform the key generation. The script will make no sense with any other input device, being it a keyboard or off-the-shelf AG5.

In this sense the red and blue shift keys will be keys like 'a' or space when the firmware treats them as those. You need a translator to transform the scancodes to actual keycodes. It's a matter of convenience whether this translator is in the PC or in the AG5.

Windows and X11 have only a single 2D table that is indexed by shift state (think 1 bit per shift key) and scancode. The output is the keycode. So you can't handle sequences. shift-alt-A is the same as alt-shift-A.

My strategy was to use the original keymap, identify things I don't like and change them using autohotkey or usbhotkey. When OpenAG5 works, it simpl y means I can do the same this on any computer I plug the AG5 into.
