*Especially if you’re a beginner (or an expert), it’s frequently useful to capture the image of what’s on the screen — an error message or diagram, for example.*In Windows, PrintScreen key copies the whole screen image, as a graphic, onto your invisible Clipboard, so you can paste into an e-mail message or any other program (“This is what I’m seeing! What do I do now?!”). If you add the Alt key, you copy only the front window.
