Here's a samplte function which operates on a region. It reverses the
lines of the region, boxquotes it and titles the boxquote (needs
boxquote.el):
+-------------------------------+
|The beginning and end positions|
|of the marked region. |
+-------------------------------+
X
/ \
/ \
(defun reverse-boxquote-region (BEG END)
(interactive "r") ;; <-- "r" means: "Operate on a region"
;; see C-h f interactive RET
(reverse-region BEG END)
(boxquote-region BEG END)
(boxquote-title "Reversed and boxquoted region"))
Bye,
