The key to taking screenshots is the "Show all your open windows" button, which looks like a box with two lines to the right side of it. It'll be in the top row of your keyboard, and may also be labeled as F5.
Here's how to use that button to take screenshots in two ways.
• To take a screenshot of the entire screen: Press the Ctrl key and the "Show all open windows" button at the same time.
• To take a screenshot of a part of the screen: Press the Shift and Ctrl keys, as well as the "Show all open windows" button, then use your cursor to click and drag a box around the area you want to screenshot.
When you take any kind of screenshot, you'll see an image of the screenshot appear at the bottom of your screen.
Your screenshot will appear in the bottom right corner of the screen.
This will give you the option to open the screenshot by double clicking the pop-up and then selecting the screenshot from your Files folder.
However, if you need to see an older screenshot, you can do so by clicking the circular button in the bottom-left corner of your screen, selecting the up-carrot button and then clicking "Files."
Click on "Files" to find other screenshots.
Within the "Files" folder you may have to access the "Downloads" folder to locate your screenshot.
Screenshots are saved in .png format.
