Portion of a keyboard

FIG. 1 is a perspective view of the portion of a keyboard showing my new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a side elevational view of the right side thereof;

FIG. 4 is a side elevational view of the left side thereof;

FIG. 5 is an elevational view of the front side thereof;

FIG. 6 is an elevational view of the rear side thereof; and,

FIG. 7 is a perspective view thereof similar to FIG. 1 including illustrations of more environmental elements.

The designations of right, left, front and rear are for reference purposes only. The different shading used to distinguish the L-shaped hand rest portion from the main body of the keyboard is intended to depict a contrast of appearance only, and does not depict any particular color, material or texture. The broken line showing of the keys, the rear portion of the keyboard and its round buttons in all the drawings, and the bottom of the keyboard in FIGS. 3-7, and the elements in FIG. 7 is for illustrative purposes only and forms no part of the claimed design.
