Screenshots are handy. You can use them to show your grandparent how to use a new app. You can use them to send a shot of that strange error message to your company’s IT department. You can use them to capture tweets — yours or someone else’s — before they disappear down the deletion black hole.

If you’re using an iPhone, you’ll find that taking a screenshot is a very simple operation. The process differs slightly depending on whether you’re using a recent-model iPhone or an older one with a Home button (such as an iPhone SE or an iPhone 8).

• If you’re using a recent iPhone without a Home button, press the side button and the volume-up button simultaneously.
• If you have an iPhone that has a Home button, press the side button and the Home button instead.
• You’ll get a thumbnail image of your screenshot in the lower-left corner.
• Tap on the image to make it larger. Icons in the upper-right corner let you delete it or share it. There will also be editing tools below that will let you add highlights or mark it up. Click on the plus sign in the lower-right corner, and you can add text, a signature, arrows, or various shapes. If you’ve taken more than a single screenshot, you can edit each individually.
• When you’re finished, tap Done in the upper-left corner. You can save the image to Photos, Files, or a Quick Note; you can also copy and delete or just delete all the screenshots.
