Print Screen

Finally learned how to print screen on iMac OS X today. I wasn't actively searching for this tip but as soon as I found it, I remembered the few times I had tried to print screen and failed. Now I am all set whenever I need it in the future. There are some cool options on this feature if you use some additional keys to the Shift-Command-4 combination, so if you are a stranger in a strange land like me, check it out.
