The most important use of the Home button is to take you to the Home screen, which houses all of your app icons. If you’re inside a particular app, you can hit the Home button to exit the app, revealing the Home screen. But there are many other iPad features that you activate using the Home button.

The Home Button Is Your Gateway to Siri

Siri is Apple’s voice-activated personal assistant. It can perform many tasks, including finding nearby restaurants, setting alarms, and opening apps. Activate Siri by pressing the Home button for several seconds until you hear two beeps. A display of multicolored lines will flash on the bottom of the screen, indicating that Siri is ready to listen to your command.

Quickly Switch Between Apps or Close Apps

The iPad has ways to open apps that are much quicker than hunting through page after page of icons searching for the right one. The fastest way to get back to an app you recently used is to launch the multitasking screen by double-clicking the Home button. This screen shows you windows of all of your most recently opened apps. You can slide your finger back and forth to move between the apps and tap an app to open it. If it’s one of the most recently used apps, it may still be in memory and will pick up where you left off. You can also close apps from this screen by using your finger to swipe them up toward the top of the screen. As with any screen on the iPad, you can get back to the Home screen by clicking the Home button again.

Take a Screenshot of Your iPad

You can take a screenshot of your iPad by pressing down on the Sleep/Wake button and the Home Button at the same time. The screen will flash, and a camera sound will play when your iPad takes the picture.

Activate Touch ID

If you have a recent iPad (that is: iPad Pro, iPad Air 2, iPad Air, iPad mini 4, or later), your Home Button also has a fingerprint sensor on it. Once you have Touch ID set up on your iPad, you can use a finger to do many things, such as opening the iPad from the lock screen without typing in your passcode and verifying that you want to buy something in the app store.

Create a Shortcut Using the Home Button

One trick you can do with the iPad is creating an accessibility shortcut using the Home button. You can use this triple-click shortcut to zoom in on the screen, invert the colors, or have the iPad read you the onscreen text. Here’s how to set it up.
