It's far less the control key than the meta key for me.
I don't use emacs except once in a blue moon, but do use readline / emacs-style bash commandline editing. The ctrl-mapped features (and yes, I swap capslock/ctrl) are easy. The meta ones ... not so much.
As a random bit of trivia, tapping esc followed by another key counts as hitting meta for that key. It might be easier to simply slap 'esc x' than try to chord alt-x.
