| 28 | ;; Flyspell is a minor Emacs mode performing on-the-fly spelling | |
| 1d8a80f0 | 29 | ;; checking. |
| 3215afc4 | 30 | ;; |
| 1f44857f | 31 | ;; To enable Flyspell minor mode, type M-x flyspell-mode. |
| 65a5c06a | 32 | ;; This applies only to the current buffer. |

33 | ;; |
| 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. | |
