I would say the correct behavior is to combine the modifier and the “shift”ed
result. C-S-a should be C-A. But my memory is fuzzy as to whether nsterm
should do this or it happens in emacs generic code. And if
ns-alternate-modifier is ‘none’, then there is no such thing as C-M-letter,
just C-letter, where the identify of ‘letter' is determined by what comes from
opt-<original-key>.
