Thank you Eric and Jambunathan Eric: i tried with the added backslash but that dosent seem to work as well, would you mind testing the snippet below on your system? is it still something wrong im doing? ;test (font-lock-add-keywords 'org-mode '(("\\b[Ss]alt\\b)" (0 '(:weight ultra-bold :foregroun "#FF9800") t)))) Jambunathan: hi-lock-mode looks interesting and i will investigate it soon, is it per file settings, or can you define a word/fg-bg rule that will apply to all files? thanks alot guys, really appreciate it!
