Appending Kills

   Normally, each kill command pushes a new entry onto the kill ring.
However, two or more kill commands in a row combine their text into a
single entry, so that a single `C-y' gets it all back as it was before
it was killed.

   Thus, if you want to yank text as a unit, you need not kill all of it
with one command; you can keep killing line after line, or word after
word, until you have killed it all, and you can still get it all back at

   Commands that kill forward from point add onto the end of the
previous killed text.  Commands that kill backward from point add text
onto the beginning.  This way, any sequence of mixed forward and
backward kill commands puts all the killed text into one entry without
rearrangement.  Numeric arguments do not break the sequence of
appending kills.  For example, suppose the buffer contains

     This is a line -!-of sample text.

with point as shown.  If you type `M-d M-DEL M-d M-DEL', killing
alternately forward and backward, you end up with `a line of sample' as
one entry in the kill ring, and `This is text.' in the buffer.  (Note
the double space, which you can clean up with `M-SPC' or `M-q'.)

   Another way to kill the same text is to move back two words with
`M-b M-b', then kill all four words forward with `C-u M-d'.  This
produces exactly the same results in the buffer and in the kill ring.
`M-f M-f C-u M-DEL' kills the same text, all going backward; once
again, the result is the same.  The text in the kill ring entry always
has the same order that it had in the buffer before you killed it.

   If a kill command is separated from the last kill command by other
commands (not just numeric arguments), it starts a new entry on the kill
ring.  But you can force it to append by first typing the command
`C-M-w' (`append-next-kill') right before it.  The `C-M-w' tells the
following command, if it is a kill command, to append the text it kills
to the last killed text, instead of starting a new entry.  With
`C-M-w', you can kill several separated pieces of text and accumulate
them to be yanked back in one place.
