When using your home computer scrolling within boxes and lists on web pages is simple. You just move the on-screen pointer on to scrollbar, click and hold the left mouse button and move the scrollbar up and down.
Now if you encounter a scrolling box or list while surfing on your iPhone in Safari and you try to scroll with your finger, you’ll find that the entire page scrolls, instead of just the box. The trick here to scrolling such areas is to use two fingers. Placing two fingers on the area you want to scroll is the desktop equivalent of the click and hold action. When your done just go back to one-finger scrolling.
