Abstract
A keyboard having multiple layouts includes depressible keys. A light reflector is positioned under at least some of the depressible keys with light sources configured to emit light towards the light reflectors. The light impinges on one of a plurality of reflective surfaces of the light reflectors and is reflected towards a corresponding depressible key under which the light reflector is positioned to cause a character or symbol to appear on a surface of the depressible keys. A switch allows a user to selectively control the character or symbol appearing on the surfaces of the depressible keys, resulting in more efficient input for the multiple layouts that improves the user experience.
