That'd be [C-backspace], if you're using the vector notation. Note we're
talking about the DEL _character_, not the key labeled Del(ete). It's
the Backspace key that usually sends DEL in the terminal (also note that
the example speaks about deleting all _preceding_ whitespace). I suspect
"the control delete key" wording comes from times when the keyboards
were somewhat different from those of today.

But it's only an example, so all this perhaps doesn't matter. I just
thought I'd mention the semantic shift introduced by the change, sorry.
