It's not nice to downvote a factual statement (that there is some advice that just doesn't work) without providing a counter-argument. Seriously, vim doesn't handle maps for ctrl-1, ctrl-2, etc. or ctrl-shift-[, etc. because terminals don't have a way to represent them to running programs. (Technically, xterm has a mode, but no programs understand it.) And gui vim doesn't handle them (though, it could) because that would be too different from what terminal vim can do.
