Most ergonomic keyboard layouts fall into two categories: unibody (or Alice) and split. The former is a single board with the two halves of the keys rotated about 30 degrees apart at the bottom. The separation forms an A-shaped space between the keys — which has nothing to do with why it’s called an Alice layout, it’s just a happy coincidence. This subtle tweak pushes your elbows away from your ribs while keeping a straight line from your forearm to your middle knuckle. Using one, I pretty instantly felt more open along the front side of my body. This layout more closely resembles a traditional keyboard, so it should be easier for most folks to get used to than a fully split option.
