What Is the Keyboard Shortcut to Take a Screenshot?
Take a screenshot on your Windows computer by pressing the Windows and Print Screen keys, and on your Mac OS X computers by pressing the Command, Shift and 3 keys at the same time. On a touchscreen Windows device, press the Windows logo and the Volume Down key simultaneously.
Both systems save the screenshots automatically. Find your Windows screenshot in the Screenshot folder under Pictures, and your Mac OS X screenshot on the Desktop. Pressing only the Print Screen key takes a screenshot and copies it to the memory. Press Control+V in an image editor to paste it. Press Command+Shift+4 on a Mac to take a screenshot of a part of the screen, then drag the cursor to select an area.
