Robert: It seems that R-CTL and any numeric key generates the X'00' character.
Can't tell from the code, but uncommenting some old DEBUG output, it looks like I see the R-Ctl go down, then the nueric key and then the reverse as they go up.
So for R-Ctl-2 I only see a Keycode/Scancode of 32/20, not 32/03.
As you are aware, debugging in the KB trap is extremely difficult, but if this is just to try and provide for entering a true NULL (X'00') character, why would we bother? Who actually wants to TYPE a NULL character?
If R-Ctl-(numeric) is supposed to be a NULL, then why doesn't any normal KB entry program support it?
Or is this just a 'curiosity' question?
