This section describes higher-level commands for yanking, which are
intended primarily for the user but useful also in Lisp programs.
yank-pop honor the
yank-excluded-properties variable and
property (see Yanking).
This command inserts before point the text at the front of the kill
ring. It sets the mark at the beginning of that text, using
push-mark (see The Mark), and puts point at the end.
If arg is a non-
nil list (which occurs interactively when
the user types C-u with no digits), then
yank inserts the
text as described above, but puts point before the yanked text and
sets the mark after it.
If arg is a number, then
yank inserts the argth
most recently killed text—the argth element of the kill ring
list, counted cyclically from the front, which is considered the
first element for this purpose.
yank does not alter the contents of the kill ring, unless it
used text provided by another program, in which case it pushes that text
onto the kill ring. However if arg is an integer different from
one, it rotates the kill ring to place the yanked string at the front.
This command replaces the just-yanked entry from the kill ring with a different entry from the kill ring.
This is allowed only immediately after a
yank or another
yank-pop. At such a time, the region contains text that was just
inserted by yanking.
yank-pop deletes that text and inserts in
its place a different piece of killed text. It does not add the deleted
text to the kill ring, since it is already in the kill ring somewhere.
It does however rotate the kill ring to place the newly yanked string at
If arg is
nil, then the replacement text is the previous
element of the kill ring. If arg is numeric, the replacement is
the argth previous kill. If arg is negative, a more recent
kill is the replacement.
The sequence of kills in the kill ring wraps around, so that after the oldest one comes the newest one, and before the newest one goes the oldest.
The return value is always
If this variable is non-
nil, the function
its value instead of
delete-region to delete the text
inserted by the previous
yank-pop command. The value must be a function of two
arguments, the start and end of the current region.
insert-for-yank automatically sets this variable
according to the undo element of the
text property, if there is one.
