How do I take a screenshot of my Chromebook in Tablet mode?
Your keyboard will be disabled in tablet mode. You can capture the screen in tablet mode the same way you would on an Android smartphone. Press and hold the Volume down and Power button for 1 second to take a screenshot.
The screenshot will be stored in the Downloads folder. You can access this folder by pressing the Alt and J keys at the same time, or you can select the launcher icon in the lower left corner and select File > Downloads.
