You plug the dongle on your computer (PC, TV, ...), set to "On" the keyboard is recognized by the system and it works! You plug in and it works! What the people demand more? Minimal footprint. Well balanced keyboard. An integrated touchpad with 2 buttons for mouse clicks and double tap recognized. A "left click" button conveniently placed on the top left of the keyboard to make it easier scrolling of such web pages. Exactly what I needed. Very Satisfied!
