26 | ;; Flyspell is a minor Emacs mode performing on-the-fly spelling | |
1d8a80f0 | 27 | ;; checking. |
3215afc4 | 28 | ;; |
1f44857f | 29 | ;; To enable Flyspell minor mode, type M-x flyspell-mode. |
65a5c06a | 30 | ;; This applies only to the current buffer. |
3215afc4 GM |
31 | ;; |
32 | ;; To enable Flyspell in text representing computer programs, type | |
1f44857f DL |
33 | ;; M-x flyspell-prog-mode. |
34 | ;; In that mode only text inside comments is checked. | |
