I added this to my .emacs:
(defun t-face ()
"to pass org-footnote automatically to toggle-face"
(interactive)
(toggle-face 'org-footnote))
(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))))
