With my return to daily coding, my wrists and left pinky are hurting while using my Apple keyboard. I ended up getting a Kinesis, which is long overdue. I also broke out my old Logitech thumb trackball. It’s working OK, but I might try one of their new versions.
@bjhess Oh, I missed the most important part: mousefix.org. That helps you use additional buttons on your mouse. I use Spaces on the Mac, which is part of what makes it tempting to upgrade my trackball to have forward and back buttons, which could be programmed to switch Spaces.
