On-the-fly spell checker
Flyspell is a minor Emacs mode performing on-the-fly spelling checking. To enable Flyspell minor mode, type M-x flyspell-mode. This applies only to the current buffer. To enable Flyspell in text representing computer programs, type M-x flyspell-prog-mode. In that mode only text inside comments and strings is checked. Some user variables control the behavior of flyspell. They are those defined under the `User configuration' comment.
