DvorÃ¡k, in addition to designing an ultimate efficiency keyboard, developed a bunch of keyboard layouts for the handicapped. One of these was for left handed typing only. And apparently, people who spent the time to learn the layout could type at speeds of over 60 words a minute.
This keyboard was clearly designed for two distinct sets:
1. People with no right hand
2. Autocad users
With a right hand on the mouse and the left hand gracefully navigating the keys, Autocad efficiency would go through the roof!
