INTRODUCTION | 11 ■ Multi-finger horizontal swipe (iPad only) —When multiple apps are simultaneously running, swipe several fingers from left to right or from right to left on the screen to switch between the active app and the other apps that are currently running in the background (using the app switcher). Alternatively, iPad and iPhone users alike can access the app switcher to quickly switch between apps by quickly pressing the Home button twice. TIP Apple continues to make navigating around your favorite apps with taps, finger gestures, and swipes easy. For example, on any screen where you’re scrolling downward, such as when you’re surfing the Web with Safari, you can simply tap on the time that’s displayed at the top center of the screen to quickly return to the top of the page or screen. Meanwhile, if you’re in the process of typing something on your iPhone and don’t like what you typed, instead of pressing and holding the Delete key to delete your text, simply shake the smartphone in your hand for a second or two to “undo” your typing. Be sure to turn on this Shake to Undo feature by launching Settings and tapping Accessibility. TIP You can also easily interact with the iPhone using just one hand. When using the iPhone 6/6s/6 Plus/6s Plus, double touch (use a gentle tap, as opposed to pressing) the Home button, and everything that’s displayed on the screen shifts downward, so you can more easily reach it with your thumb. Plus, as you’re reading emails, you can use your thumb (on the hand you’re holding the iPhone with) to swipe left or right across an Inbox message listing to manage that incoming message. HOME BUTTON QUICK TIPS Here’s how to use some of the Home button’s main functions when using iOS 9: ■ Activate Siri —Press down and hold the Home button for 2 seconds from the Home screen or when using any app. ■ Access the app switcher —From any app (or from the Home screen), quickly press the Home button twice. Press the Home button again (or select an app) to exit the app switcher. ■ Exit an app and return to the Home screen —When using any app, press the Home button once to exit it and return to the Home screen. Keep in mind, in most cases this does not shut down the app; it will continue running in the background.
