How do you take a screenshot?
PC Users
PC users can take a screenshot of anything displayed on their screen by pressing the "Print Screen" button on their keyboard, opening an image editing program (such as Photoshop or MS Paint) and then simultaneously pressing [Ctrl] [V] on their keyboard to paste the screenshot in the editing program. The screenshot can then be saved to the user's computer.
PC users may also use a paid-application called "SnagIt" which allows users to specify the area they would like to screenshot. SnagIt is available for a free 30-day trial download.
Mac Users
Mac users can take a screenshot of anything displayed on their screen by simultaneously pressing the buttons [CMD] [Shift] [4] on their keyboards. The screenshot is automatically saved as a PNG image on the user's desktop. The user can double-click the PNG image to display the image in Mac's image viewing application called "Preview."
