kill-whole-line

kill-whole-line is an interactive compiled Lisp function in `simple.el'.

It is bound to <C-S-backspace>.

(kill-whole-line &optional ARG)

Kill current line.
With prefix ARG, kill that many lines starting from the current line.
If ARG is negative, kill backward. Also kill the preceding newline.
(This is meant to make C-x z work well with negative arguments.)
If ARG is zero, kill current line but exclude the trailing newline.
