Tp4's left hand bottom row on dat Ergodox, is, --- z x b c v --- this way control-c and control-v feels natural.
For right hand config instead of reaching for Y with index top left, also moved it, right hand bottom row --- n m y , . ---
You do have to relearn these few keys, but I can switch between my Ergodox and normal keys and maintain 100% speed, but Tp4 is way older, so he has had the time to become a weirdo.
The arrangement of the keys can change by alot due to the wrist angle changing alot.
Feel free to experiment and come up with your own layout, There are no rules. Make your own. That's the whole point of keyboard exploration.
