I don't know about his keyboards, but many now have meta switches to turn the ~jkl; block area into a num pad. Then you don't have to move your right hand to input numbers. Left hand holds the meta key; right hand inputs numbers. On my Kinesis Advantage 3, I think the number 1 or 2 meta key on the left side of the board is set up this way.
