Microsoft Natural Ergonomic Keyboard 4000. Natural Ergonomic Keyboard 4000 has been expertly crafted to allow you to work in a more natural position. The new Gull Wing design features a 14-degree gable, a natural arc and a curved key bed – bringing the keys closer to your fingers to reduce reach and unnecessary motion, while encouraging a more natural typing position.
