Point-of-sale terminals often require changeable keybuttons to allow for reconfiguration of the functions of the keyboard. For example, a common change is to make a total key by joining together two adjacent single key positions on a keyboard. Reprogramming of the keyboard identifies the two adjacent keys when simultaneously pushed as a new function. Ordinarily, a new keybutton top is used to replace the two existing keybuttons. The new double-wide top will be fastened to each key stem. However, on curved keyboards or in situations where it is not desired to replace the two individual keybuttons, a new approach has been designed. Fig. 1 illustrates a typical standard keyboard with two key positions having keybuttons 1 each with an independent removable key lens top 2.
