A useful keyboard shortcut that I use when I write code is CONTROL+OPTION+COMMAND+8 which inverts the colors on the screen. It makes it a lot easier on the eyes IMO.

If you want to take a full screenshot hit COMMAND+SHIFT+3 or if you want to crop where the screenshot will be taken hit COMMAND+SHIFT+4 then you can click and drag a square around the area you want.
