You can take a picture of your screen (a screenshot). This is useful if you want to show someone how to do something on the computer, for example. Screenshots are just normal picture files, so you can email them and share them on the web.
Take a screenshot
To take a picture of what's on your screen:
Go to the Dash and open the Screenshot tool.
In the Take Screenshot window, select whether to grab the entire desktop, a single window, or an area of the screen. Set a delay if you need to select a window or otherwise set up your desktop for the screenshot. Then choose any effects you want.
Click Take Screenshot.
If you selected Select area to grab, the pointer changes into a crosshair. Click and drag the area you want for the screenshot.
In the Save Screenshot window, enter a file name and choose a folder, then click Save.
