Arguably one of the most requested items from the backers of the Librem 15 rev2 was for a backlit keyboard. We are proud to announce that keyboard design request did in fact make it into the Librem 15 rev2. You can see from the photo below, on the brightest setting, illuminating around and through the keys.
Function + F10 toggles between the three modes, off, brighter, and brightest levels.
Note: the Librem 13 does not have the backlit keyboard, the next revision (within two years time) is planned to.
