Talk about getting out of your comfort zone and learning something new. I thought I had better teach myself how to do a screen shot if I was going to attemt the upcoming tutorial I have planned.
When you have your screen a way that you would like to share it (such as a Photoshop shot), press the Prt Scr located just above the Backspace.
Now go to Start > All Programs > Accesories > Paint. When Paint opens up right click in the open space and click Paste. Now all you need to do is save it in My Pictures (or whatever you use to upload photos to Blogger).
That's it. Pretty easy I hope.
