Ubuntu: Configure a Keystroke to Take a Screenshot

The Mac OS has a nice screenshot interface. You press Cmd Shift 3 to take a screenshot of the entire screen and save it to the desktop. Pressing Cmd Shift 4 will display a crosshair to take a screenshot of any rectangle area of your choosing. This saves the step of cropping the image which you are most likely going to do.

You can replicate this exact functionality in Ubuntu Linux without installing anything else.

  1. Go to System -> Preferences -> Keyboard Shortcuts
  2. In the desktop section, find Take a screenshot and highlight it
  3. Press Ctrl Shift 3 (or whichever combination you would like)

There is no entry for “Take a screenshot of an area”, so we must create it.

  1. Click the Add button
  2. Name: Take a screenshot of an area
  3. Command: gnome-screenshot -a
  4. Click the newly created entry
  5. Press Ctrl Shift 4 (or whichever combination you would like)
  6. Close the window

Thats it! Now you can press Ctrl Shift 4 and take a screen shot of an area.
