Take a Screenshot
Ever need to take a screenshot of something on your screen? Maybe it’s an error, maybe it’s just a graphic, but you need it…but how? Easy. Command-shift–3 will take a picture of the entire screen and command-shift–4 will let you select a part of the screen or a window. Of course if you want to step things up, just download Skitch for free and crank up your screenshots a few notches.
