The Dvorak Simplified Keyboard ( ) is an alternative way of putting letters on an English keyboard. Most English keyboards have the keys lined up in a "QWERTY layout." The point of QWERTY was to prevent typewriter keys from sticking, but it is not the most "ergonomic", or comfortable, keyboard to type on. August Dvorak invented the Dvorak keyboard, where letters are arranged based on how often they are used. For instance, the most common letters (like "e") are in the center row of keys, so less hand movement is needed when a person is typing.
