Doing:
"." 1 NTHTOKEN --> Isolate the key
"." 2 NTHTOKEN --> Isolate the shift plane

I think it's simpler than using SUB to get the key value and plane. Not simpler than IP/FP though (hard to beat that).

I wonder if perhaps we might benefit from an NTHCHAR command (assuming the three, single-character format I proposed). 1 NTHCHAR for the key, 2 NTHCHAR for the shift, and 3 NTHCHAR for the modifier. I think it would be fairly simple to code and (negligibly?) faster than NTHTOKEN and it keeps the return string to exactly 3 characters.
