摘要： A cushioning apparatus for reducing the impact felt by the fingertips of a typist using a keyboard. A conventional keyboard includes a plurality of keys, each corresponding to at least one character or number, and each having a hard keytop. According to the invention, a pad is attached or applied to each keytop, each pad being substantially softer than the associated hard keytop. Each pad has a flat top surface, with a legend thereon indicating the keytop to which it is attached. Each pad also has a flat bottom surface, with adhesive applied thereto, and a single sheet of release paper removably applied to the adhesive for all the pads, the adhesive being provided for attaching the pad to the respective keytop, or to the top of another pad, to provide additional thickness of padding.
