Switch between Full Screen Mode and Window Zoom. Triple-tap with three ngers, then tap
Window Zoom or Full Screen Zoom in the zoom controls that appear. To choose the mode that’s
used when you turn on Zoom, go to Settings > General > Accessibility > Zoom > Zoom Region.
Resize the zoom window (Window Zoom). Triple-tap with three ngers, tap Resize Lens, then
drag any of the round handles that appear.
Move the zoom window (Window Zoom). Drag the handle on the edge of the zoom window.
Show the zoom controller. Go to Settings > General > Accessibility > Zoom, then turn on Show

tap the oating Zoom Controls button to zoom in or out, single-tap the button to display the
zoom controls, or drag it to pan. To move the Zoom Controls button, tap and hold the button,
then drag it to a new location. To adjust the transparency of the zoom controller, go to Settings >
General > Accessibility > Zoom > Idle Visibility.
Have Zoom track your selections or the text insertion point. Go to Settings > General >
Accessibility > Zoom > Follow Focus. Then, for example, if you use VoiceOver, turning on this
option causes the zoom window to magnify each element on the screen as you select it using a
swipe in VoiceOver.
Zoom in on your typing without magnifying the keyboard. Go to Settings > General >
Accessibility > Zoom, then turn on Follow Focus and turn o Zoom Keyboard. When you zoom in
while typing (in Messages or Notes, for example), the text you type is magnied, but the entire
keyboard remains visible.
Display the magnied part of the screen in grayscale or inverted color. Triple-tap with three
ngers, then tap Choose Filter in the zoom controls that appear.
While using Zoom with an Apple Wireless Keyboard the screen image follows the insertion point,
keeping it in the center of the display. See Use an Apple Wireless Keyboard on page 27.
Invert Colors and Grayscale
Sometimes, inverting the colors or changing to grayscale on the iPod touch screen makes it
easier to read.
Invert the screen colors. Go to Settings > General > Accessibility > Invert Colors.
See the screen in grayscale. Go to Settings > General > Accessibility > Grayscale.
Turn on both eects to see inverted grayscale. You can also apply these eects to just the
contents of the zoom window—see Zoom on page 139.
Speak Selection
Even with VoiceOver turned o, you can have iPod touch read aloud any text you can select.
Turn on Speak Selection. Go to Settings > General > Accessibility > Speech. There you can also:
•
Adjust the speaking rate
•
Choose to have individual words highlighted as they’re read
Have text read to you. Select the text, then tap Speak.
You can also have iPod touch read the entire screen to you. See Speak Screen, next.
