Unlike Windows Explorer, Finder doesn't offer an obvious way to paste in a path to easily change folders. Instead, there's a Go menu with several options for opening special folders like Desktop, Home, etc.
I learned there's an option for "Go to folder..." that brings up a pretty terrible dialog box to paste in a path.
This dialog can be accessed using Cmd-Shift-G.
As I said in my previous post, I've never used Finder much, but things like this make it a little more likely that I will use it more.
