A slight update to my previous post on ergonomics:  when I changed the location of my monitor (by mounting it to the wall) I moved my keyboard closer to the edge of the desk, thinking that was a good distance from my eyes to the monitor.  However, after a few weeks of unconsciously moving the mouse to the edge of the desk to match where the keyboard was, I realized that my wrist was hurting.  When the mouse is close to the edge, my wrist rests on the edge and isn’t at a good angle.  Oops!  I moved the keyboard a bit further back and am conscious to keep the mouse even further from the edge, and things are much more comfortable.

I expect that the whole thing will be more comfortable when I get to shortening the desk, but I haven’t finished that yet!
