Hello! I am wondering if anyone can share me a working code snippet which adds font-lock keywords to org-mode via 'font-lock-add-keywords'. The following is my code (which does not work):

(font-lock-add-keywords 'org-mode '(;; TODO wrapped between whitespace ("\\s-TODO\\s-" 0 '(t :foreground "orange") 'prepend) ;; FIXME wrapped between whitespace ("\\s-FIXME\\s-" 0 '(t :foreground "deep pink") 'prepend) ;; REVIEW wrapped between whitespace ("\\s-REVIEW\\s-" 0 '(t :foreground "orchid") 'prepend) ;; COMMENT wrapped between whitespace ("\\s-COMMENT\\s-" 0 '(t :foreground "turquoise") 'prepend) )) A basically identical piece of code works for emacs-lisp-mode but not org-mode — and I have no idea why.

Any help?
