When i type, my most annoying habit is that i hit the semicolon instead of the single-quote. And sometimes, i hit the el (no, not the train you silly Scrabble player) as well. So, i often type don;lt, or isn;t, and the like. Never seems to happen when i reach for the double-quote though. I wish i knew how to break the habit. Electroshock feedback?
Any suggestions? Or, what's your most annoying habit whilst typing?
