Many young programmers think that their bottleneck is typing speed. After some experience one realizes that it is not the case, you have to think much more than type.

At some point my room-mate forced me to turn of the light (he sleeps during the night). I had to learn to touch type and I experienced an actual improvement in programming skill. The most surprising was that the improvement not due to sheer typing speed, but to a change in mindset. I'm less afraid now to try new things and refactor them later if they work well. It's like having a new tool in the bag.

Have anyone of you had similar experience?

Now I trained a touch typing a little with KTouch. I find auto-generate lessons the best. I can use this program to create new lessons out of text files but it's only verbatim training, not auto-generated based on a language model.

Do you know any touch typing program that allows creation of custom, but randomized lessons?
