Hi John and Eric,

I decided to adopt your approaches, thanks for the suggestions.  So I can use either the response: or ++ to highlight changes in our manuscripts.

Cheers,
M

#+BEGIN_SRC emacs-lisp
(org-link-set-parameters
 "response"
 :export (lambda (keyword desc format)
           (cond
            ((eq 'latex format)
             (format "\\textcolor{red}{%s}" keyword))))
 :face '(:foreground "red"))
#+END_SRC


#+begin_src emacs-lisp
(setq org-emphasis-alist
      (cons '("+" '(:foreground "red"))
            (delete* "+" org-emphasis-alist :key 'car :test 'equal)))

(custom-set-variables
  '(org-latex-text-markup-alist '((bold . "\\textbf{%s}")
					 (code . verb)
					 (italic . "\\emph{%s}")
					 (strike-through . "\\textcolor{red}{%s}")
					 (underline . "\\uline{%s}")
					 (verbatim . protectedtexttt))))

#+end_src
