"C-x 6" is the perfect prefix for tab commands because it's easier to remember as continuation of the sequence with window prefix "C-x 4" and frame prefix "C-x 5": C-x 4 - window commands C-x 5 - frame commands C-x 6 - tab commands > I'd like to avoid backward-incompatible changes if possible. Actually it's not quite backward-incompatible because it's still available after loading two-column.el. Also please read this comment in two-column.el that admits it's not mnemonic: ;; This one is for historical reasons and simple keyboards, it is not ;; at all mnemonic. All usual sequences containing 2 were used, and ;; f2 could not be set up in a standard way under Emacs 18.

Even with > PuTTY (which generally emulates xterm), C-TAB yields nothing in Emacs. And [backtab] can't be used even on xterm, because it's bound to other commands in some modes, e.g. to Info-prev-reference in Info-mode.
