To rotate the screen on a Chromebook, press Ctrl + Shift + Refresh (the circular arrow key on the top row). Each time you press the shortcut, the screen rotates 90 degrees. You can also change it manually by opening Settings > Device > Displays > Orientation and selecting the preferred rotation option such as 90°, 180°, or 270°. This feature is useful for tablets, presentations, reading, or fixing an accidentally rotated screen quickly.
