I type those, and others like ctrl-W, ctrl-U, ctrl-F, ctrl-B, ctrl-D,
ctrl-R, etc, reasonably often, but I don't encounter them in files,
unlike the ones I named. (I have checked-in files at github with embedded
terminal control sequences.) So those _feel_ different. The stty
settings are just defaults, and can be changed. There's nothing special
about the characters. The ones I use in vi, not in stty, are are not
changable, but are based on mnemonics instead of ASCII meaning. I use
ctrl-F for "forward page" not for ACK.

The stty ones:
    intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
    eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z;
    rprnt = ^R; werase = ^W; lnext = ^V; discard = ^O;

Of those that have settings, only discard do I not use. Stop, I use, but
usually by accident and then I have to start again. I'd like that one to
default to undef, but I log in to too many computers per day to bother
trying to manually set it. Reprint, escape next (lnext), and quit I use
fairly rarely, but when I need them there's no substitute.

Oh, wait, you're thinking of Windows short cuts. I don't think they are
meant to map to a character _ever_. Those are just key press events
caught by the OS / program, same as command keys in Macs.

Ctrl-C for Copy I think exists because Command-C for copy first existed.
Neither has anything to do with the ASCII control character ETX.

I like tab separated values more than comma separated values, because
with rare exceptions[*], tabs in text can be converted to spaces without
loss of meaning, so I can have a separator that never needs quoting. But
using ASCII RS (ctrl-^) for it's intended purpose as a record separator
just feels obsolent and wrong to me, even if it is even less likely to
appear in the sort of things I put into TSV files.

[*] And the sorts of things that do need raw tabs, like Makefiles, I
    don't put in TSV files.
