The first thing you will notice about this keyboard is its embedded trackball on the upper right corner. According to the manufacturer, this is the first keyboard in the world to have an integrated laser trackball and a scroll wheel. Trackballs work just like mice and can use either a mechanical or an optical sensor, and on this keyboard the optical technology (“laser”) is used. On the left upper corner there are two buttons and a scroll wheel.

You can configure the trackball resolution at 400 dpi, 800 dpi or 1200 dpi. This is done by pressing the function (“Fn”) key together with the F9, F10 or F11 keys. At a higher resolution the cursor moves faster on the screen.

There are several other function keys available: MCE, My TV, My Videos, My Music, My Pictures, Record TV, DVD, rewind, fast forward, Ch+ and Ch-, plus other typical keyboard functions like Insert, Home, Page Up, Page Down and End. These functions work out of the box with multimedia players, not requiring any kind of software to operate.

Besides the function keys, Aurora Micro Wireless has also seven multimedia keys that also work on Windows XP and Windows Vista without any driver: home, e-mail, zoom, volume up, volume down, mute and play/pause.
