Edgar,

Thank you for the proposition.

What is the difference with:

;; ajouter une colorisation pour mes notes @ dans le texte
(setq font-lock-keyword-org-extra-comments
     '(("(@[^)]*)\\|@([^)]+)\\|@[^\s\n\r]+"
        (0
         '(:background "light yellow"
           :foreground "red")
         prepend))))

;; Add this after having required org-mode
(font-lock-add-keywords 'org-mode
                      font-lock-keyword-org-extra-comments
                      t)

(require 'org)


in terms of mechanism

My understanding is that I'm calling the function when I enter org-mode, with 
the hook, so it simulates the permanency by calling the function on file 
opening, correct?
