-Twidor was originally written by researchers studying
-[chording keyboard learning and performance](http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.4.3606&rep=rep1&type=pdf). Their
-research suggests that learners may achieve faster typing speeds on single-handed chording keyboards than two-handed QWERTY keyboards given equal amount of practice.  In article [2] below, Lyons states, "faster typists would reach
-60 WPM, the rate of our expert, after 10,000 phrases
-(approximately 80 sessions or 27 hours) while the slower typists
-could achieve 45 WPM."
