A plurality of keys are received within the plurality of key recesses of the keyboard housing. The plurality of keys each have a generally square configuration. The keys each have an upper end and a lower end. The lower end has a pair of recesses formed therein. The recesses each have a light disposed therein. The upper end is divided into two sections. The two sections each correspond with one of the lights of the pair of recesses. Each of the two sections have illuminatable indicia disposed thereon.
