iPad Tip 17 - Better Zooming

The Zoom accessibility option that's in the iPhone OS is even more helpful on the iPad than

| Accessibility | Zoom by flipping Zoom to On.

The Zoom screen explains the three options: double tap with three fingers to zoom in; drag
with three fingers for panning around the screen; and use three fingers to double tap without
releasing, and then drag up or down to zoom in or out.
