Ergonomic keyboards typically fall into two categories: Alice and split keyboards. The former is a single unit with an A-shaped gap in the center of the keys. Split models come in two separate pieces which you can arrange as you like on your desk. Additional ergonomic features like tenting and negative tilt can make typing feel even more comfortable, and are often available on both Alice and split boards. Tenting raises the middle of the keys up so your hands take on more of a “handshake” position. Negative tilting lowers the top of the keyboard to keep your wrists angled downward instead of back towards your forearms.
