There are several options on how you can take a screenshot from a personal computer. Depending on your hardware or the computer you are using (Mac, Windows, or Google Chrome), you can take screenshots differently. For Windows and Google Chrome, you can either use the windows icon plus the prt sc (print screen) menu or alt plus prt sc.
If you are using a Mac, you can screenshot by clicking Cmd plus Shift plus 3 together. If you are unsuccessful on these options, you can just use the snipping tool found on your start button or windows icon. Click new and then choose from either free-form, window, or full-screen snip. When you are using the first two snips, drag your mouse to the area you want to capture and then click save.
