Screen Capture: If you ever want to capture what is on your screen, for example if you need to show an error message, simply press the "Prt Scr" button (Windows) which is unsually located to the right of the "F12" key at the top of your keyboard. Nothing will display to say you have successfully completed the screen capture, but that is ok. Open a program such as Word. You can then go to "edit" and choose paste, or hold the "Ctrl" key and hit "V". The image of what was on your screen will appear. You can then save this for future reference.
