U just saved me like HOURS of pressing buttons and fiddling with combinations on the keyboard!!.. i have doing my utmost to figure this simple lil thing out on the track pad! i can't even begin to tel you how frustrating it was on an HPmini.. i accidently locked the trackpad and was in midst of transfering files and what not. finally got fed up enough to google it ..and you were the 1st link I seen and i clicked on it! and whala!! back in business..
