How do I take a screenshot on Mac and PC?
To take a screen shot on Mac, simply press command+shift plus 3 (to screenshot the full screen) or 4 (to screenshot a part of the screen). If you press four, drag your cursor over the part of the screen you wish to capture, then release and the screenshot should appear in your desktop.
To screenshot on Windows, click on the window you would like to capture. Press Ctrl + Print Screen. The Print Screen key is near the upper-right corner of your keyboard. Click the ‘start’ button in the bottom left of your screen and open Paint. When the program loads, hold Crtl+V to place the image into the paint window. Click ‘file’, and ‘save as’. In the ‘save as’ window, select where you want the screenshot to be saved, give it a name and click ‘save’.
