Yep.

Fair enough, but once you're over the surprise you might actually find
it useful to tell Ctrl+Backspace from Ctrl+H. Also, having
Ctrl+Backspace bring up the help in emacs is rather surprising too.

Finally, the suggestion of ^_ follows the pattern that the Ctrl
modifier masks off all but the lowest 5 bits of the unmodified
character code, i.e.:

Ctrl+A -> 0x41 & 0x1F -> 0x01 (^A)
Ctrl+Space -> 0x20 & 0x1F -> 0x00 (^@)
Ctrl+Backspace -> 0x7F & 0x1F -> 0x1F (^_)
