> Renaming: I think if the enter key does anything except execute/open the selected file it's non obvious and nonsensical.

In a vacuum, sure, I could agree with that. But in conjunction with cmd + [arrow] to move in and out of your current position, I think cmd + down to open a file continues that line of thought and is intuitive and obvious in the Finder context. After drilling down with cmd+down, if it's another directory, open it, else if it's a file... open it.

Alt-up and enter to do similar navigation all make sense in their own individual context, but in the context of each other or Explorer itself, is not intuitive and is nonsensical imo. That would be like mouse wheel down to scroll, but ctrl+up to scroll the other way. And F2 I guess, as you put it, is just pure randomness and would make no sense in any context.
