> Yeah accidentally switching that one caused some grief the first week as I fumbled for the "right" button to dismiss it. But Having to use it is not my experience. Does the previous generation insist you use it?

You're right, it can be dismissed that way. I looked for a way to disable it completely and quickly found that wasn't possible, but I did discover the right-arrow trick you mentioned. But it doesn't make it disappear for long, and I never managed to build up the reflex of pressing it regularly (it's kind of non-obvious, you have to admit), and to be honest I'd mostly forgotten right-arrow did that. But thank you for reminding me, I may have to try to work on that muscle memory.
