Thumb Scrolling is a means of controlling a smart phone using only ones thumb, on the hand they are holding the device in.
Thumb scrolling is they way in which a user of Secret Takeaways can use the app using only one hand, because all the key clicks are in reach of your thumb. The other-hand therefore is free to hold a slice of pizza, a cold beer, etc.
