Type to Learn Software to teach Keyboarding Skills

Their are numerous typing to learn programs available for students with varying disabilities.  This website lists many different programs made for students with learning disabilities and/or physical disabilities (e.g. can only use one hand for instance or are blind).  http://www.abledata.com/abledata.cfm?pageid=19327&ksectionid=19327&top=11214

For example, Keyboarding by Ability ($150)  helps individuals with the use of one hand (or as little as three fingers) learn to type  through guided practice.  They are taught  how to maneuver their hand over the keyboard through progressively challenging lessons that build upon another.  Learning is reinforced through quizzes and drills that can be timed at 1, 3, and 5 minutes.  Giving students with varying disabilities quicker ways to type is increasingly useful in our technology driven world.  I can see this being helpful for a number of students in the high school as so much of what we do uses a computer.
