@nimakro I also find the navigation keys, pgup/pgdn/home/end to work extremely well, especially when you flip switch 3, which causes CapsLock to function as Fn. I feel less fatigue because I strain my hands less due to the reduced need to move my hands. The fingers can reach almost everywhere without moving my hands. The feel of it is also fantastic, so I just feel better when I use it. This can't really be explained, nor underestimated.
