Thanks Eric , really appreciate the continuous help!

i do plan to get into rexeg on the future (i promise :)) but real life now
just allow me to allocate time (i started an assistant professor position
and time is at a huge premium..).

i tried using this as i tried to understand from your email, but i guess im
again doing something wrong. shouldn't the below example color "salt", it
dosent see to work.

;test
(font-lock-add-keywords
 'org-mode
'(("\b[Ss]alt\\b)" (0 '(:weight ultra-bold :foregroun "#FF9800") t))))

thank you for all your help
