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 window that appears, choose what to take a picture of.
You can take a picture of the whole of the screen (Grab the whole desktop), just the window that you're currently using (Grab the current window), or you can select an area of the screen by dragging a box around it (Select the area to grab).
Click Take Screenshot.
If you selected Select area to grab, the cursor will change into a cross. Click and drag the area you want for the screenshot.
The Save Screenshot window will now appear. Choose where to save the screenshot and click Save.
