Bindings:
\\[ispell-word]: correct words (using Ispell).
\\[flyspell-auto-correct-word]: automatically correct word.
\\[flyspell-auto-correct-previous-word]: automatically correct the last misspelled word.
\\[flyspell-correct-word] (or down-mouse-2): popup correct words.
Hooks:

Remark:
`flyspell-mode' uses `ispell-mode'. Thus all Ispell options are
valid. For instance, a personal dictionary can be used by
invoking `ispell-change-dictionary'.
Consider using the `ispell-parser' to check your text. For instance
consider adding:
\(add-hook 'tex-mode-hook (function (lambda () (setq ispell-parser 'tex))))
in your .emacs file.
\\[flyspell-region] checks all words inside a region.
