Install the following defun, put the cursor on fontified text and do M-x
toggle-face.
(defun toggle-face (&optional face-from)
(interactive (list (read-face-name "Face" (face-at-point))))
(let ((f (assq face-from face-remapping-alist))
(face-to 'default))
(if f (setq face-remapping-alist (delq f face-remapping-alist))
(push (cons face-from face-to) face-remapping-alist))))
