When you’re in laptop mode, decide whether you want to take a partial or whole-of-screen screenshot. For partial screen, press Ctrl + Shift + F4 Overview Mode. For the whole-of-screen, press Ctrl + F4 Overview Mode. On a tablet, press the power button and the volume down button. You can also take a screenshot using the Pixelbook pen: For a partial screenshot, select the pen icon, then Capture Region, then drag across the area of the desired screenshot and lift when done. For a whole-of-screen screenshot, select the pen icon and then Capture Screen, for the whole screenshot.
