This video in the Electronics category will show you how to fast scroll on your Android. Let's assume you have a lot of contacts and out of them you want to find one in a hurry and you have only one hand free. Instead of scrolling down the entire contact list with your thumb, you can press the scroll thumb called the fast scroll feature, jump down to the letter of your choice and then find it in that. When you are travelling in a new place, bring up the maps, choose 'my location' and you will know exactly where you are. It's really cool!
