Let’s say you need to take a snap of your entire screen. To do this you press the ‘Ctrl’ and ‘Window Switcher’ keys at the same time:
If you just want to capture a specific area of the screen just add shift to the key combo, like so:
After hitting the shortcut the screen will briefly flash white and a notification to confirm its success (or failure) will follow in the lower right corner of the screen. Clicking on the notification will open the Chrome OS file manager. All screenshots are saved as high-quality .PNG files, and stored in the Downloads folder for easy retrieval. This notification also has a copy to clipboard button for easy copying and inserting into a Google Doc or email.
Don’t forget to check for, hide or obscure any sensitive information, like e-mail addresses or embarrassing photos, before uploading your screenshots to the web.
