If you look at process_message() in gui_w48.c (Windows Gvim) and
decode_key_event() in os_win32.c (Win32 console Vim), you'll find some
special-case handling:
/* Ctrl-6 is Ctrl-^ */
/* Ctrl-2 is Ctrl-@ */
/* Ctrl-- is Ctrl-_ */
I added the remapping hack for console Vim nearly 15 years ago, mostly
because I couldn't stand typing Ctrl-Shift-6 to toggle between
buffers.
The other Ctrl-<numeral> combinations are discarded, presumably
because they have no ASCII equivalent.
