Old Emacs
=========
Until ispell becomes part of the standard emacs distribution, you
will have to explicitly request that it be loaded. Put the following
lines in your emacs init file See init file: (emacs)init file.
(autoload 'ispell-word "ispell" "Check the spelling of word in buffer." t)
(autoload 'ispell-region "ispell" "Check the spelling of region." t)
(autoload 'ispell-buffer "ispell" "Check the spelling of buffer." t)
(global-set-key "\e$" 'ispell-word)
(It will do no harm to have these lines in your init file even after
ispell is installed by default.)
