Claim Text:
1. An apparatus comprising: a keyboard comprising a plurality of alphabetic keys each bearing at least one character, the keys disposed in an evenly spaced grid pattern with respect to one another such that columns of the alphabetic keys are coaxially vertically aligned, and wherein the alphabetic keys have keycaps that each have a left side and a right side and that are each provided with bilaterally-nonsymmetrical tactile features that are horizontally offset from one another from one row of the alphabetic keys to the next, such that the bilaterally-nonsymmetrical tactile features of the alphabetic keys for a first row of the alphabetic keys are oriented towards the left side and the bilaterally-nonsymmetrical tactile features of the alphabetic keys for a next-adjacent row of the alphabetic keys below the first row of the alphabetic keys are all oriented towards the right side, and all of the keys have the same keycap form factor, and the peripheral key shape is distinct from the bilaterally-nonsymetrical tactile features.
