I just updated my 2009 Macbook Pro to Mavericks yesterday. Everything is going well so far, except for some reason, I can no longer use command+↑ to open the parent folder in a new window. On Lion it worked fine. Now, it simply goes to the parent folder in the same window. Does anyone know how to change that? I went into preferences and de-selected "open new folders in tabs," but that didn't change anything. It's quite annoying as now I have to manually go in and open each folder; I often drag documents from folder to folder and it's much easier to just command+↑ and drag to the parent folder than double clicking each time to open them separately. Any ideas? am I missing something obvious?
