26 ;; Flyspell is a minor Emacs mode performing on-the-fly spelling
27 ;; checking.
28 ;;
29 ;; To enable Flyspell minor mode, type M-x flyspell-mode.
30 ;; This applies only to the current buffer.
31 ;;
32 ;; To enable Flyspell in text representing computer programs, type
33 ;; M-x flyspell-prog-mode.
34 ;; In that mode only text inside comments is checked.
35 ;;
36 ;; Some user variables control the behavior of flyspell. They are
37 ;; those defined under the `User variables' comment.

59 Non-nil means use highlight, nil means use minibuffer messages."

66 Detection of repeated words is not implemented in
74 "A list of exceptions for duplicated words.
75 It should be a list of (LANGUAGE . EXCEPTION-LIST).
77 LANGUAGE is nil, which means the exceptions apply regardless of
78 the current dictionary, or a regular expression matching the
79 dictionary name (`ispell-local-dictionary' or
80 `ispell-dictionary') for which the exceptions should apply.
82 EXCEPTION-LIST is a list of strings. The checked word is
83 downcased before comparing with these exceptions."

101 This only happens if `flyspell-sort-corrections' is non-nil. The

103 to be sorted, and the third parameter is the word that's being

120 "The maximum distance for finding duplicates of unrecognized words.
121 This applies to the feature that when a word is not found in the dictionary,
122 if the same spelling occurs elsewhere in the buffer,
123 Flyspell uses a different face (`flyspell-duplicate') to highlight it.
124 This variable specifies how far to search to find such a duplicate.

202 The third is either the symbol `doublon' or the list
203 of possible corrections as returned by `ispell-parse-output'.

206 incorrect."

213 This is passed to the `ispell-change-dictionary' when flyspell is started.
214 If the variable `ispell-local-dictionary' or `ispell-dictionary' is non-nil
215 when flyspell is started, the value of that variable is used instead

513 Flyspell mode is a buffer-local minor mode. When enabled, it
514 spawns a single Ispell process and checks each word. The default

526 Remark:
527 `flyspell-mode' uses `ispell-mode'. Thus all Ispell options are
