Same here. I only use the middle 3 fingers on each hand and I don't need to look at the keyboard to type. Typing speed is good enough at about 70–80 wpm. I do note that due to my inconsistent finger use, I make some mistakes but they don't really bother me: I'd rather become at adept at editing text more efficiently. Fixing typos is really no different from fixing a bad word choice or bad grammar.
