While I agree that using the mouse input for the checklist would be better, the current ALT + Arrows does not conflict with the P3D menu commands at all.

That's good. Very good, can you please inform me how you can press the "Alt" key without the sim in P3D displaying the sim menu bar across the top. And further how to depress an arrow key in combination with the alt key without the sim scrolling through the menu?  I would really like that information if you could share it.
