The Print Screen key, is often abbreviated as Print Scrn.
Print Scrn key copies everything on your screen.
In Windows, the sole function of this key is to take a snapshot or picture
of your computer screen and copy it to the clipboard. It does not cause the
printer to print anything.
"Under earlier command-line based operating systems, this caused an exact
copy of the current screen output to be sent to the standard printer port,
usually LPT1. In essence, whatever was currently on the screen when the key
was pressed was printed."
Alt key+ Print Scrn key
[[Will take a screenshot of the currently selected window, not the entire
screen like the normal screenshot function. This allows you to target that
specific window that you have open and nothing else. No more cropping those
screenshots to grab the content you were after!]]
You have to paste the image in to Paint, Wordpad, Word or some other program
that will handle images.
