Take it from someone who averages 140 WPM and peaks at 160-170 WPM. Don't skip errors and return to them later. Do delete whole words (alt-backspace) and re-type them from the beginning. When you get really fast, almost all typing errors are transposition errors. By the time they register you are already several characters, even words, ahead. Trying to correct them character by character will throw you off.

If you use emacs, what do you think about `flyspell-auto-correct-previous-word`? It's like autocorrect, but it only happens when you invoke it and it always happens on the last misspelled word rather than the word under point.

Never tried it but that sounds like it could work great.
