Screenshots and screencasts
You can take a picture of your screen (a screenshot) or record a video of what's happening on the screen (a screencast). This is useful if you want to show someone how to do something on the computer, for example. Screenshots and screencasts are just normal picture and video files, so you can email them and share them on the web.
Take a screenshot
Install the Screenshot application from the App Center, under the Utilities category, and open it.
In the Take Screenshot window, select whether to grab the whole screen, the current 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.
Alternatively, import the screenshot directly into an image-editing application without saving it first. Click Copy to Clipboard then paste the image in the other application, or drag the screenshot thumbnail to the application.
Quickly take a screenshot of the desktop, a window, or an area at any time using these global keyboard shortcuts:
Prt Scrn to take a screenshot of the desktop.
Alt+Prt Scrn to take a screenshot of a window.
Shift+Prt Scrn to take a screenshot of an area you select.
When you use a keyboard shortcut, the image is automatically saved in your Pictures folder with a file name that begins with "Screenshot" and includes the date and time it was taken.
You can also hold down Ctrl with any of the above shortcuts to copy the screenshot image to the clipboard instead of saving it.
Some keyboards will have a Print Screen button near the top right hand corner. Press it once to take a screenshot.
Make a screencast
You can make a video recording of what is happening on your screen:
Press Ctrl+Alt+Shift+R to start recording what's on your screen.
A red circle is displayed in the bottom right corner of the screen when the recording is in progress. This indicator does not show up in the video.
Once you've finished, press Ctrl+Alt+Shift+R again to stop the recording.
The video is automatically saved in your Videos folder with a file name that starts with "Screencast" and includes the date and time it was taken.
