Screenshot on a Chromebook

Here is real easy way to take a screenshot on a Chromebook without having to install an extension.

Press "ctrl + shift + Switch to Next Window Key."  This will pull up a set of crosshairs that you can use to select a region of the screen for your screenshot.  The screenshot is then temporarily saved into your "Downloads" folder.  Just remember that if you log off or shut down the Chromebook all of your downloads are deleted.
