This was frustrating for me as I often rotated the screen without meaning to. If you have a physical mouse, not a touchpad, that's your best bet, as accidental rotations are going to be minimized. Using a touchscreen with this would not be ideal, as this seems to result in a lot of accidental rotations for me. Whatever method you use, pick a very easy pack to ensure you have plenty of time, and be as deliberate and careful as you can be.
