I have Colemak at power-on, Qwerty-toggle on the top-outermost index position on each hand, and a third layer, which I seldom use, for the right-hand numpad. It was 5 hours of soldering for an out-of-practice fellow like me. The hundred-and-some SMD diodes
should be thrown far into the woods gave me some years back on my technique.
This purchase amounted to 350 USD in 2015.
Once the Ergodox was programmed and in daily use, I found no need to favour sore wrists.
After a short time spent considering how this fit in with my desk, my mouse snuck in between the two halves. There wasn’t room to the right, but that desk-estate in the middle there is lucky.
A larger desk, like my 2016 office desk would be better.
Also five keys for each hand and attached to my chair would be
handy closer at hand handsome good for my posture.
On second thought, it would be six keys per hand, there being a palm button.
