Abstract: A removable keyboard cap extension apparatus for a data processing system entry keyboard having a number of data entry keys which are constructed to electronically convey data. The removable keyboard cap extension apparatus includes a keyboard cap adapted to fit onto a key among a plurality of keys for use by a user of a particular data processing application among a number of data processing applications. The removable keyboard cap extension apparatus has a body that includes an upper planar surface, wherein the body and its upper planar surface are elevated above the data entry keys such that the upper planar surface is enhanced larger than the data entry key. The removable keyboard cap extension apparatus can be connected to an individual data entry key, or can replace the data entry key. A depression at any point on the upper planar surface will actuate only the individual data entry key which the removable keyboard cap extension apparatus is connected or replaces.
