 $ stty -a | tr ';' '\n' | fgrep ^

 intr = ^C
 quit = ^\
 erase = ^?
 kill = ^U
 eof = ^D
 start = ^Q
 stop = ^S
 susp = ^Z
 rprnt = ^R
 werase = ^W
 lnext = ^V
 discard = ^O

Some of the above are shadowed by readline or by bash in emacs mode,
but the tty driver uses more than a few control keys.
