As far as I can tell, emacs[0] denoted control as 'C' first. The tmux docs most likely follow that trend. I'm only starting to learn emacs, so haven't yet come across any key combos that require a capital letter 'C' preceded by Ctrl. Will be interesting to see how that's represented.

Ctrl is always a modifier.

So "C" is the letter C, "C-x" is ctrl-x, "C-c" is Ctrl-c, and there's no ambiguity. You can't bind anything to Ctrl on its own.

"xev" differs. And xmodmap.

Fair. I was talking specifically about emacs.

Clearly ^ is superior to C in every way.
