How to Take a Screenshot

If your iPad has a home button, press the top and home buttons simultaneously and then quickly release both. Your iPad will take a screenshot, and you’ll see a thumbnail at the bottom left of your screen.
You can tap the thumbnail to open your screenshot or swipe left to view it later.
If your iPad does not have a home button, press the top button and any of the two volume buttons simultaneously and quickly release both. If you’re successful, you’ll see a little thumbnail of your screenshot in the lower-left part of your screen. You can tap on it to open it or swipe left to dismiss it.
