You have to remember to press the ALT key when moving the cursor on the ECL, but once you get used to it, you should be fine. I'm pretty sure that pressing the arrow keys without holding the ALT key will not cause the A/P to relinquish control, so that's a good thing.

And yes, I did try it, but I'm prone to doing strange things just to see what happens (just not in v1.5). :D
