kill your region with some kill func (check elisp man)
and store it (A)
Be sure to remember the position of your text.
,----
| ELISP> (setq A "aaa bbb ccc ddd")
| "aaa bbb ccc ddd"
| ELISP> (setq A (split-string A))
| ("aaa" "bbb" "ccc" "ddd")
|
| ELISP> (setq A (reverse A))
| ("ddd" "ccc" "bbb" "aaa")
|
| ELISP> (mapconcat #'(lambda (x) x) A " ")
| "ddd ccc bbb aaa"
`----
And now insert the new text at the saved position.
