A short while back I had a small sports accident and injured my left thumb quite badly, to the point that my left hand needs to be left alone to heal. As a software engineer, this presents a major challenge.
I decided to look into one handed typing layouts. Mechanical Keyboards have been making huge leaps and bounds with hardware and sofware design, and as a corollary folks have gotten VERY deep into ergonomic keyboard layout design and scientific optimization based on biomechanics.
After some initial research, I found two layouts optimized specifically for one handed typing:
The community around Frogpad seemed a little less engaged, so I joined the Artsey.IO discord server and started diving into the layout. I picked up a Boardsource 3x4 macro pad and flashed Artsey.IO on it.
The training is slow, but it's better than not being able to type at all.
