Doesn't seem there is one, so I wrote it for you: > (defun buffer-narrowed-p () > "Return t if buffer is narrowed, nil otherwise." > (or (> (point-min) 1) > (< (point-max) (buffer-size)))) Sometimes you can't avoid assuming that buffer positions start at 1, but that's rare. Even in the above case, for example, you can simply check: (defun buffer-narrowed-p () (> (buffer-size) (- (point-max) (point-min)))) -- Stefan
