alt="Tip"/> If you make a mistake when you were cutting, pasting, or typing, shake the iPad. Doing so undoes the last edit (provided that you tap the Undo Paste or Undo option when it appears and keep the shake feature enabled in Settings ⇒ Accessibility ⇒ Touch ⇒ Shake to Undo).
You might also see these options:
Auto-Correct: If you happen to select a word with a typo, the iPad might underline that word. If you tap the underlined word, the iPad might show you one or more words it thinks you meant to spell (or you see No Replacements Found). Tap a suggested word to accept it.
Predict: A predictive word feature reveals up to three word or phrase options in buttons just above the keyboard. If one of these words or phrases is what you had in mind, tap the appropriate button.
Replace: The iPad might show you possible replacement words. For example, replacement words for test might be fest, rest, or text. Tap the word to substitute it for the word you originally typed.
Indent Right or Left: Pretty self-explanatory. With this option, you can indent highlighted text to the right or left.
Look Up: Tap your selected word for a definition, courtesy of the New Oxford American Dictionary, the Oxford Dictionary of English, an Apple dictionary, or a foreign language dictionary if you’ve downloaded any dictionaries onto your iPad. Look Up goes well beyond definitions and includes searches that extend to the App Store, Apple Music, Twitter, the web, Wikipedia, and more.
Multitasking
Through multitasking, you can run two or more apps simultaneously and switch from one app to another. The following examples illustrate what multitasking enables you to do on your iPad:
A third-party app, such as Slacker Personal Radio, can continue to play music while you surf the web, peek at pictures, or check email. Without multitasking, Slacker would pause the moment you opened another app.
A navigation app can update your position while you’re listening to, say, Pandora internet radio. From time to time, the navigation app will pipe in with turn-by-turn directions, lowering the volume of the music so you can hear the instructions.
If you’re uploading images to a photo website and the process is taking longer than you want, you can switch to another app, confident that the images will continue to upload behind the scenes.
You can leave voice notes in the Evernote app while checking out a web page.
Double-press the Home button (if your iPad has one) or swipe up from the bottom of your screen to display App Switcher. You see thumbnail versions of your open apps. Scroll to the left to see more apps. Tap the thumbnail for the app you want to switch to; the app remembers where you left off. If you hold the tablet sideways in landscape mode, as shown in Figure 2-5, the previews for your apps appear sideways, too.
To remove an app from App Switcher, drag the app’s thumbnail up and beyond the top of the screen. Poof — it’s gone.
Now let’s look at some other tricks that make multitasking even more powerful.
FIGURE 2-5: App Switcher shows you the apps you’ve recently used or are still running.
Splitting the screen
You can exploit all that gorgeous screen real estate on your iPad to make multitasking even more productive.
Split view
For starters, there’s a feature called split view, which enables you to display two app windows onscreen at the same time, with each app getting half the screen.
Launch the first app you want to use and then tap the app’s multitasking icon: the three dots in the top center of the app window (see Figure 2-6). This displays the multitasking menu, a version of which is pointed out in Figure 2-6. Tap the split view icon, and then tap the icon of other app you want onscreen. Now the second app is running side by side with your first app! Split view mode is shown in Figure 2-6. Drag the gray resizer bar between the two apps to resize them.
The split view feature works with Apple’s own apps and some third-party apps. If you don’t see the multitasking icon, it means the app doesn’t support split view.
FIGURE 2-6: iPadOS split view in action with Safari on the left and Mail on the right.
I bet you can think of all sorts of reasons to run two apps at the same time. Maybe you’re composing a message to a friend in the Mail app while scrolling through Safari in the smaller panel to find a place to have lunch. Or perhaps you’re sketching in one app while using a photo in another as a reference point.
When you’re finished with split view, tap the multitasking icon in the app you want to use and then tap the full screen icon.
Slide over
Another way to get two apps to share the screen at the same time is the slide over feature. Instead of running side by side, as in split view, with slide over one app runs full screen and a second app runs in a window that takes up about a third of the screen width. This second window is in slide over mode, which means it runs on top of the full-screen app and can be dragged to the left or right side of the screen, as needed.
To give slide over a whirl, first launch the app that you want to run in slide over mode. Tap the app’s multitasking icon (labeled in Figure 2-6) to display the multitasking menu, and then tap the slide over icon (again, see Figure 2-6). iPadOS shrinks the app window and displays the Home screen. Tap the icon of the app that you want to run full screen. This second app opens normally and the slide over app remains onscreen on top of the full-screen app.
When you’re finished with slide over, tap the multitasking icon in the slide over app and then tap the full screen icon.
The slide over feature works with Apple’s own apps and quite a few third-party apps. If you don’t see the multitasking icon, it means the app doesn’t support slide over.
