the w580 shake control its actually a sensor that senses when it has been moved from its original place,, kinda of like a laser toa ball and if the ball moves it changes songs,,,,,, u cant turn the aplication of or on, u can just not use it without pressing and holding the W key,, if u wish to use it just press and hold the W key and flick it sideways so it actually registeres a movement and changes song
