Emacs commands to wrap a block of text into start/end tags, or insert them. Similar to what AUC-TeX' font commands do, but generic.
(defun wrap-region-in (start-text end-text)
"Insert START-TEXT at the beginning of the currently active
region, and END-TEXT at the end of it."
(let ((start (min (point) (mark)))
(end (max (point) (mark))))
(save-excursion
(goto-char end)
(insert end-text)
(goto-char start)
(insert start-text))))
