If you’re looking to grab a shot of you’re beautiful desktop and capture the whole screen, you simply need to press Command-Shift-3. Looking to select the area you want captured? Command-Shift-4.

But now I’m gonna tell you about the ever so useful third option. Hold down the Command, Shift, and 4 keys, then press the Spacebar, a small camera icon appears. When you move this camera icon over the element you’d like to capture, that element is highlighted. Click and you’ve captured a screenshot of just that element — no further cleanup required.
