OS X Screen Capture!
Some apple keyboard users may have noticed the lack of a “Print Screen” key.. Never fear, there is a print screen function in OS X, and it’s far superior to the Windows version! (this tip comes from This Great Source)
CMD + Shift + 3
This will take a screenshot of your entire screen. - Saved to Desktop PDF
CMD + Shift + 4
This will bring up a selection tool so you can make a rectangular screenshot of a certain area. - Saved to Desktop PDF
CMD + Shift + 4 + Space Bar
This will turn your cursor into a tiny camera. Use this camera to take a picture of the Dock, a menu, or a window and it will crop the background automatically for the resulting image. - Saved to Desktop PDF
Note: If you hold down the Control key during and of the above commands the image gets copied to your clipboard, ready to paste, rather than creating a PDF on your desktop.
