Using the Command key to find the path of your folder
Here's an under-utilized, but handy trick that has been around in the Mac OS for a very long time and fortunately it's made it's way into OS X.
By Command-clicking on a Window's title bar and you'll get a pop-up menu that shows the hierarchial path to the root level of the drive that the folder is on. Not only is this great way to quickly see where a folder resides on your computer, it's also great way to quickly navigate UP the folder hierarchy. If you want to quickly navigate DOWN the folder hierarchy then you'll want to be in column view in OS X or use one of the many shareware utilities that provide this function.
