Killing a whole balanced expression can be done with @kbd{C-M-k}
-(@code{kill-sexp}) or @kbd{C-M-@key{DEL}} (@code{backward-kill-sexp}).
-@kbd{C-M-k} kills the characters that @kbd{C-M-f} would move over, and
-@kbd{C-M-@key{DEL}} kills the characters that @kbd{C-M-b} would move
-over. On some machines, @kbd{C-M-@key{DEL}} typed on the console is a
-command to reboot; when that is so, you cannot use it as an Emacs
-command. This conflict is rare, though: usually the @key{DEL} key for
-Emacs is really @key{BACKSPACE}, and the reboot command is
-@kbd{C-M-@key{DELETE}}, so there is no conflict.
