Those far keys are usually triggered by your weakest fingers -- return, for example, is triggered via your pinky and can often require you to stretch your pinky (and ulnar nerve) in unergonomic ways, leading to Cubital Tunnel Syndrome.

I find that a good introductory layout to this kind of keyboard is the Kinesis Advantage 2 [1]. As you can see a bunch of common keypresses usually delegated to the pinkies have been set on the thumb clusters. On my Ergodox, I also have symbols layers that allow you to reach common symbols without moving my fingers significantly from the home row. It definitely takes an adjustment period but my RSI definitely thinks its worth it!

This is exactly why I love my Ergodox. My biggest hand issue was pinky pain, and with the ergodox I've moved basically all of the 'stretch' pinky keys to thumb/index finger. In particular moving backspace/enter/ctrl to the thumb cluster makes me feel like I can never use a keyboard without one again. It's completely eliminated pinky pain on both of my hands.
