copy-region-as-kill function works in much the same way as
kill-region function (see
kill-region). Both are written so that two or more kills in
a row combine their text into a single entry. If you yank back the
text from the kill ring, you get it all in one piece. Moreover, kills
that kill forward from the current position of the cursor are added to
the end of the previously copied text and commands that copy text
backwards add it to the beginning of the previously copied text. This
way, the words in the text stay in the proper order.
copy-region-as-kill function makes
use of the
last-command variable that keeps track of the
previous Emacs command.
