IMHO stupid to put the most common operation on a file behind a meta key. The ratio of how often I rename a file (rarely) vs use a file (often) doesn't come out in favor of this choice. That said I realize the decision was probably made long long ago and now Apple is just stuck with it. Still though. Maybe after another few years I'll figure out the hot key to change between the side pane and the main file list. (yes I could just look it up, but I do most of my work in terminal and I try to avoid Finder as much as I can, I really dislike using it)
