Screen Shots

You may need to capture what is shown on your screen to share with someone else.

The method for capturing a screen shot varies by operating system.

• Windows 10: You can either use a keystroke, or the Snip & Sketch tool. See this CNet Page for more details.
  • Keystroke
    • Pressing the Print Screen key will copy the current screen to the clipboard, so you can paste the image where you want it.

    • Pressing Alt + Print Screen together copies the current window to the clipboard.
