just press print screen once while viewing what you want to copy, try it now, literally right now, just press it once quickly. Now open paint, and paste it in, either ctrl+v or by using paste in the menu. You can do that with virtually anything. If it does not work for some reason, try your f-lock (or scroll lock, one of those keys we hardly ever use can alter it) key, then try the process again.

Edit: Keyboard shortcuts are amazing sometimes Farmtalk, there's many for many different applications. Fahrenheit symbol, as in it was 84° here today, simply Alt+248 on the number pad will make a Fahrenheit° symbol.
Have fun
