CMD + UP to up one dir in finder. Maybe I've got messed up settings or something, I don't know, but when I want to go up a folder I don't see a button or a an item called ".." that can be clicked. Did this drive anyone else nuts?
I have generally made the 3-pane view my default for this very reason (which has obvious left-right semantics for hierarchy traversal). I think maybe you can also command click the folder-name header? I think I once knew about CMD+Up but my general workflow is in the terminal these days, so Finder is mostly only used for selective-file-move/copy operations, and even then, called from terminal. It’s usually `open path1; open path2` then select and drag.
