Print Screen Button - A general Tutorial

There are plenty of you out there who do not know what the Print Screen button is. So for your reference, I am providing this tutorial that shows where it is and how to use it. :)
Below I have provided you a picture of a keyboard, with the Print Screen button outlined in Red. It could be there or anywhere around that place.
What the Print Screen button basically does is take a picture of a entire screen that is appearing in your computer and basically if your press Ctrl + V, it can be pasted in any image editing program including Paint. After that you can resize, crop, etc. your print of the Screen however you want. When something has be Print Screened its called a Screenie. Beloe is a screenie I made of my blog front page.
