This is a full featured mini thumb keyboard, which includes keys to control video and audio, a touchpad like you see on laptops, all 12 "F" keys, and left/right mouse buttons on top of the unit for use when playing games. It has 3 colors of backlighted keys, very handy for use in a darkened room like a home theater. Our home theater projector includes Android and internet access directly, so this keyboard enables showing youtube and other online streaming programs and movies directly to the projector screen.
It came with a USB receiver dongle. It can be run using AAA batteries, though it has built in Nokia rechargable battery which is recharged using the included USB charging cable. It is very useful for our purpose.
