im pretty sure that stands for print screen...but i have no idea how to get that key to work. isnt it supposed to take a screenshot? if so, how do u view the picture, or w/e thx

it copies the full screen to your clipboard. You just need to paste it somehwere. Like paint. Alt+ prntscrn takes a screenshot of window in focus.

Pretty much like NF said, you'll need to paste it into something, specifically an image editor like Paint or Photoshop.
