Taking a screenshot on a Chromebook (and other devices)

Here's a question that's popping up a lot: "How do I take a screen capture/screenshot (i.e., an image of my screen) on a Chromebook?"

It's often useful to snap a picture of what's on your device's screen.
On a Chrombook, this is done by pressing the Ctl key together with the "Switcher" key (so called, because it otherwise switches you from tab to tab in Chrome)

Here's how to do it on other devices:

• On Windows computers, the Snipping Tool (in Accessories) does this nicely.  
• On a Mac, you can use Command-Shift-4
• In iOS (e.g., iPhone) or Android, hold the power/sleep button and home button (or volume down if your Android doesn't have a home button) at the same time.
