I just noticed that I only type correctly-ish with my left hand. My
right hand jumps all over the place to type with the index and middle
finger only, except for enter/shift with the pinky and backspace and
slash with the ring finger.
I thought for a while about why this might be — right hand is used to
moving over to the cursor keys and mouse, maybe? — and then I realized
that the other thing I do that builds finger strength is playing bass:
four fingers on the left hand, two on the right.
I’m slowly retraining myself, but boy does it feel weird to have to
think about how to type now, especially on IRC.
