Maybe like this...
(defun rs-toggle-T-and-F ()
"Toggle the characters `T' nor `F' at point."
(interactive)
(let ((case-fold-search nil))
(cond ((looking-at "T")
(delete-char 1)
(insert "F"))
((looking-at "F")
(delete-char 1)
(insert "T"))
(t (message "Neither `T' nor `F' at point")))))
Bye, Reiner.
