While using Zoom with an Apple Wireless Keyboard (see “Using an Apple Wireless Keyboard” on
page 27), the screen image follows the insertion point, keeping it in the center of the display.
Turn Zoom on or off: Go to Settings > General > Accessibility > Zoom. Or, use Triple-click Home.
See “Triple-click Home” on page 153.
Note: You can’t use VoiceOver and Zoom at the same time.
Zoom in or out
Double-tap the screen with three fingers. By default, the screen is magnified
200 percent. If you manually change the magnification (by using the tap-
and-drag gesture, described below), iPhone automatically returns to that
magnification when you zoom in by double-tapping with three fingers.
With three fingers, tap and drag toward the top of the screen (to
increase magnification) or toward the bottom of the screen (to decrease
magnification). The tap-and-drag gesture is similar to a double-tap, except
you don’t lift your fingers on the second tap—instead, drag your fingers on
the screen. Once you start dragging, you can drag with a single finger.
Move around the screen
When zoomed in, drag or flick the screen with three fingers. Once you start
dragging, you can drag with a single finger so that you can see more of
the screen. Hold a single finger near the edge of the display to pan to that
side of the screen image. Move your finger closer to the edge to pan more
quickly. When you open a new screen, Zoom always goes to the top-middle
of the screen.
