How to check for SPELLING errors in a file
Several options are available for users who want emacs to check the
spelling of their documents.
The first is:
M-x ispell
(M-x is the ALT or Compose Character key and x key pressed at the same time.)
Now the following commands are available for the duration of your emacs
session:
M-x ispell-word - Checks word
M-x ispell-buffer - Checks buffer (current file)
M-x ispell-region - Checks region
When ispell finds a word that is not in its dictionary, it will outline the
word in reverse video (from emacs it will respond with a message that says,
"Enter letter to replace word; space to flush") If there are "near misses" in
the dictionary, ispell will also display the incorrect word and a list of
correct alternatives at the top if they exist.
At this point, you can type one of the following characters:
r - Replace Word
Ispell asks you for a replacement word. Ispell will NOT
check this word.
# - Replace Word with suggested word
The words at the top of the screen are numbered. If you type
a word's number, ispell will use this word as a replacement.
<space> - Skips Word
Leave this word as is. If this word is encountered again,
ispell will stop and prompt you for an action.
a - Accept Word
Accept this word as correct for remainder of ispell session
(or emacs if you are using ispell in emacs).
i - Add Word
Add this word to your personal dictionary. This is a file
in your home directory called .ispell.words which tells
ispell to accept the word as correct every time you use
ispell (useful for things like your name).
<CTRL-G> - Quit Ispell
You can quit ispell at any time by pressing <CTRL-G>. This
is done by holding down the CTRL key and pressing "G".
The man page on ispell lists more options and gives more detailed information
on this program.

M-x spell-buffer
is a similar program to M-x ispell, but runs off of the unix "spell"
program instead of the "ispell" program. The main differences are
that spell has a larger vocabulary, but ispell offers suggestions for
replacements and allows you to add words to your personal dictionary.
----------------------------------------------------------------------
M-x flyspell-mode
is a command that is more useful to use when starting to write a
document; words will be color-coded as you type them, using the ispell
package. The first time a word that it doesn't recognize is
encountered, it's colored red, while further instances of the word are
colored yellow.
Once a word is marked as misspelled, you can click on it with the
middle mouse button to suggest replacements, or use M-TAB to
automatically correct it to what ispell thinks it should be.
