Here it is (it's a kind of "dwim" command):

(defun font-lock-update (&optional arg)
  "Updates the syntax highlighting in this buffer.
Enable Font Lock mode if it is disabled.
Otherwise, refontify the accessible portion of the buffer.
With prefix ARG, toggle Font Lock mode."
  (interactive "P")
  (save-mark-and-excursion
    (if (and (not arg) font-lock-mode)
        (font-lock-fontify-region (point-min) (point-max))
      (font-lock-unfontify-region (point-min) (point-max))
      (font-lock-mode 'toggle))))
(global-set-key (kbd "C-x x f") 'font-lock-update)
