As others have pointed out, it's fully programmable so you can have whatever layout you want. That being said, it took me about 3-4 weeks to get used to the keyboard to the point where I wasn't frustrated all the time and about 2 months to get back to my regular typing speed. One big benefit - I was developing carpal tunnel and about 6 weeks after switching to the dactyl, all pain was gone.
