The "Matias RGB Backlit Wired Aluminum Tenkeyless Keyboard for Mac - Space Gray" is an enhanced USB keyboard that does not have a number pad. It has the reliable and traditional USB 2.0 connection, with a 1 port USB 2.0 hub, space gray aluminum frame, black keycaps, and all the special Mac functionality you expect on the function keys. However, it also has RGB backlighting; this means you can turn on backlighting for times where you want more light, and use the convenient color control dial to choose any color you want for the backlighting. No software is needed.
