If you use a standard American English keyboard, do you use your right pinky to hit hyphen, equas, or backspace? I find I miss the first two more often than not, no matter how I work on it, so I often reach up with my right index finger instead. Backspace is easier to hit, being bigger and at the end of the row, but I still find myself using my right index or middle finger. I don't know why those three keys give me so much trouble.
