If you do any sort of content creation on your mac, I’m sure you have needed to take a screenshot of something at sometime. When that time came you either accomplished that task with ease due to your amazing short-cut knowledge or you didn’t.
If you didn’t conquer the previous task listen up. And even if you did, pay attention and you might learn something new.

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.
