I discovered this one by accident (thought I was pressing ALT + Print Screen) - in Windows 8 the Windows key + Print Screen takes a screen shot of the entire screen and creates a sequentially named file in the Pictures Library under a Screenshots folder!
the file type is PNG and it's one of my new favorite finds in Windows 8!!!
Thank you so much! I've been trying to figure this out and your post was extremely helpful =)
thnks ..was looking for this eveywhere..!
