Screenshot Instructions

Screenshot Instructions and Samples


  • On a PC: Press the “Alt” and “Print Screen” keys simultaneously while the window you want a picture of is active. [There really is a key called “Print Screen” near the top right of most PC keyboards!]. You now have the image in your clipboard; paste it into a blank email and send it to your instructor.
  • On a Mac: Press ⌘-Shift-4 and then drag the cursor to select the browser screen; when you let go, you’ll hear a click. You’ll now find a document on your desktop whose name begins with “Screen Shot”; email this to your instructor as an attachment.
  • On a PC (if the “Alt” + “Print Screen” method isn’t working for you): Click here for detailed instructions for creating screenshots in Windows 10.
  • On a Mac or PC, using the Firefox browser: Look for and install the browser add-on “pdfit” (it just takes a second). Once it’s installed, go to the Tools menu in Firefox, click on “Pdf It!” and then select “Save as PDF ->Visible Area”. Choose a name for the pdf (including the .pdf extension if that doesn’t automatically happen) and email it to your instructor.
  • If none of the above options work for you, try searching your computer’s Help menu for something like “Screen Shot” or “Take a picture of what is on your screen”!
