High Quality Content by WIKIPEDIA articles! The Kinesis line of ergonomic computer keyboards is an alternative to the traditional keyboard design. Most widely known among these are the contoured Advantage line, which feature recessed keys in two bucket-like hollows which allow the fingers to reach keys with less effort as well as a central array of modifiers such as enter, alt, backspace, control, etc. where they can be pressed with the thumbs. All Kinesis keyboards (except the Essential) support the capability to re-map individual keys. Recent models also come with the ability to switch between the Dvorak layout with the press of a special key combination, though keycaps printed with dual-legend QWERTY/Dvorak letters are only included on specific models. Moreover, the keys are laid out in perfect vertical rows to avoid the need for lateral movements during typing.
