2108281 9218996 PCTABS00017 A keyboard (100) for use with a standard personal computer includes an alphanumeric key array having a plurality of alphanumeric keys (102) arranged in a generally orthogonal, concave array (108, 110). A home row of keys (112, 114) defines a reference position for the fingers of the operator. A linear array of function keys (104) is provided and positioned above the reference position and titled toward the operator. A generally orthogonal array of auxiliary (106) keys is also positioned above the reference position. The array of auxiliary keys (106) is rotated with respect to the reference position to accommodate the natural angle of the thumb of the operator to the index finger. A palm rest (136, 138) is provided for receiving the palm of the operator while the operator is manipulating the plurality of alphanumeric keys. The palm rest (136, 138) is positioned above the reference position defined by the home row so that during operation of the alphanumeric keys (102), the fingers of the operator extend downward from the palm rest in a natural curved manner.
