DR.S. I am an oldster, and yet I would like to learn touch typing. Since my last comment here about a year ago aTypeTrainer4Mac went from version 1.3 to 2.0.3, steadily integrating new and useful features. In this time, I went from hunt-and-peck typing to touch typing with 100 % accuracy at an actual speed of 20 words per minute. I won't be able to participate successfully at a typing contest, but I think that the daily typing exercises help to keep my fingers and my brains in a fairly good shape...
(Version 2.0.3)
