How to take a screenshot
PC
To capture your entire screen and save the screenshot to your computer, tap the Windows key + Print Screen key. Your screen will briefly go dim to indicate that you've just taken a screenshot, and the screenshot will be saved to the Pictures > Screenshots folder.
Mac
To capture the screen tap the Command key +Shift key + 5, or by navigating to Launchpad > Other > Screenshot.
If you prefer to use old keyboard shortcuts, those are still supported. Use Command key + Shift key + 3 to capture the entire screen. If you only want part of the screen captured, Command+Shift+4 will turn the cursor into a crosshair and allow you to select the section of the screen you want to capture.
