Abstract: Keys of an electronic keyboard shaped in a novel way, in order to permit the comfortable operation of the keys, especially by a business machine operator with long fingernails. Because of those changes in the key shape and character placement, the opportunity to set the plane of use of a keyboard anterior-posteriorly into an unlimited number of positions from a strong posterior tilt to a moderate anterior tilt, is thus afforded, giving increased comfort to keyboard operators, regardless of the length of their fingernails.
