Most ergonomic keyboards fall into two categories: fully split which separates the board into two pieces, and unibody split, also known as an Alice design, which angles the keys outward at the bottom. When the keys are rotated outward or split into two halves, it allows for a wider spread between your elbows for a more relaxed typing position. Other ergonomic features, such as thumb clusters, center tenting and negative tilting are sometimes added to either type of board.
