I took the opportunity to learn an alternate KB layout (Workman) and I think that has been beneficial for my hands, which are average to slightly smaller than average, so QWERTY movements like T are a slight stretch. Have also got the split KB (Kinesis Freestyle Edge, which is OK. Would like something that can run QMK or similar). Also paying attention to the little nags and working them out is definitely valuable. For, e.g. I run 'g sta' (git status) often, as well as 'g lscm' (git log -20 --pretty etc); now I use Bash bindings to run both with Ctrl+j, and 'cls' with Ctrl+l. I've even started using the KB's 'action keys' (I.e. those ones that aren't part of the standard ANSI/layout) for Winkey+1..n to spare my left hand the awkward chord from winkey to the number row. I also run a trackball for dev and a mouse for gaming so that I split my use over different muscles. Hoping it all keeps any kind of injury at bay.
