While there are countless types of ergonomic keyboards, the most common are typically going to be angled keyboards and split keyboards. Outside of all this, there are also ortholinear keyboards. On a typical keyboard, the keys are staggered instead of being aligned upon a perfect grid. But with an ortholinear keyboard, the keys are aligned along this grid. There are both ergonomic and split ortholinear keyboards, and keyboards that use nonstandard staggering instead, like the Naya Create.
