28 ;; Flyspell is a minor Emacs mode performing on-the-fly spelling
31 ;; To enable Flyspell minor mode, type M-x flyspell-mode.
32 ;; This applies only to the current buffer.
34 ;; To enable Flyspell in text representing computer programs, type
35 ;; M-x flyspell-prog-mode.
36 ;; In that mode only text inside comments is checked.
38 ;; Note: consider setting the variable ispell-parser to `tex' to
39 ;; avoid TeX command checking; use `(setq ispell-parser 'tex)'.
41 ;; Some user variables control the behavior of flyspell. They are
42 ;; those defined under the `User variables' comment.
