This is the code Samuel refers to. It is awesome. I use it less and less ;) by which I mean everytime I use it is one less time I ever have to use it.

;; http://endlessparentheses.com/ispell-and-abbrev-the-perfect-auto-correct.html

(define-key ctl-x-map "\C-i" 'endless/ispell-word-then-abbrev)

(defun endless/ispell-word-then-abbrev (p)

"Call `ispell-word'. Then create an abbrev for the correction made.

With prefix P, create local abbrev. Otherwise it will be global."

(interactive "P")

(let ((bef (downcase (or (thing-at-point 'word) ""))) aft)

(call-interactively 'ispell-word)

(setq aft (downcase (or (thing-at-point 'word) "")))

(unless (string= aft bef)

(message "\"%s\" now expands to \"%s\" %sally"

bef aft (if p "loc" "glob"))

(define-abbrev

(if p global-abbrev-table local-abbrev-table)

bef aft))))

There's something on endless parentheses that will let you generate a correction abbrev with a keystroke.

Please forgive any typos as this was composed on a screen keyboard.
