@cindex mode, Flyspell
@findex flyspell-mode
Flyspell mode is a minor mode that performs automatic spell-checking
as you type. When it finds a word that it does not recognize, it
highlights that word. Type @kbd{M-x flyspell-mode} to toggle Flyspell
mode in the current buffer. To enable Flyspell mode in all text mode
buffers, add @code{flyspell-mode} to @code{text-mode-hook}.

does not recognize, it highlights that word. Type @kbd{M-x
flyspell-mode} to toggle Flyspell mode in the current buffer. To
enable Flyspell mode in all text mode buffers, add
@code{flyspell-mode} to @code{text-mode-hook}. @xref{Hooks}. Note
that, as Flyspell mode needs to check each word across which you move,
it will slow down cursor motion and scrolling commands. It also
doesn't automatically check the text you didn't type or move across;
use @code{flyspell-region} or @code{flyspell-buffer} for that.
