-@deffn Command kill-region start end &optional yank-handler
+@deffn Command kill-region start end
This function kills the text in the region defined by @var{start} and
@var{end}. The text is deleted but saved in the kill ring, along with
its text properties. The value is always @code{nil}.
In an interactive call, @var{start} and @var{end} are point and
the mark.
-@c Emacs 19 feature
If the buffer or text is read-only, @code{kill-region} modifies the kill
ring just the same, then signals an error without modifying the buffer.
This is convenient because it lets the user use a series of kill
commands to copy text from a read-only buffer into the kill ring.

-If @var{yank-handler} is non-@code{nil}, this puts that value onto
-the string of killed text, as a @code{yank-handler} text property.

-@code{yank-handler} properties present on the killed text are copied
-onto the kill ring, like other text properties.

@defopt kill-read-only-ok
The command does not set @code{this-command} to @code{kill-region}, so a
subsequent kill command does not append to the same kill ring entry.
-Don't call @code{copy-region-as-kill} in Lisp programs unless you aim to
-support Emacs 18. For newer Emacs versions, it is better to use
-@code{kill-new} or @code{kill-append} instead. @xref{Low-Level Kill

-@defun kill-new string &optional replace yank-handler

This function pushes the text @var{string} onto the kill ring and
makes the yanking pointer point to it. It discards the oldest entry
if appropriate. It also invokes the value of
If @var{replace} is non-@code{nil}, then @code{kill-new} replaces the
first element of the kill ring with @var{string}, rather than pushing
@var{string} onto the kill ring.

-@defun kill-append string before-p &optional yank-handler
+@defun kill-append string before-p
This function appends the text @var{string} to the first entry in the
kill ring and makes the yanking pointer point to the combined entry.
Normally @var{string} goes at the end of the entry, but if
@var{before-p} is non-@code{nil}, it goes at the beginning. This
function also invokes the value of @code{interprogram-cut-function}
-(see below). This handles @var{yank-handler} just like
-@code{kill-new}, except that if @var{yank-handler} is different from
-the @code{yank-handler} property of the first entry of the kill ring,
-@code{kill-append} pushes the concatenated string onto the kill ring,
-instead of replacing the original first entry with it.
