Have you ever run into a problem with your computer that happened to bring up an error message? Wouldn't it be nice if you could just capture that error message and send it to someone else to see if they could help you figure out what's wrong?
Here is how you can do that!
Find the Print Screen and Alt buttons on your keyboard. The PrtScn button is located on the right hand side of your keyboard right next to the Scroll Lock key. (It's also right beside the F12 key on most keyboards).
When you press the Alt and PrtScn keys at the same time, your computer will take a "snapshot" of the active window (which would be the error message).
If you want to get a shot of the whole screen, push the Shift key along with the PrtScn key and that's what you'll get.
Once you have the image captured, you can go and paste it in another program and then send it to your "computer expert" for advice! When you have the program you want to put it in open, just hit Ctrl + V to paste the screenshot (or you may have to go to Edit, Paste).
For MAC Users:
command-shift-3: capture screen to file
command-fn-shift-3: capture screen to clipboard
command-shift-4: capture selection to file
command-fn-shift-4: capture selection to keyboard
