Show the Finder Location of any Item from the Open & Save Dialog
You can instantly reveal the location of any item in the Finder from an Open and Save dialog box by selecting the item and then hitting Command+R. Regardless of the app, this will immediately switch to the Finder and open the containing folder of the item you selected. Try it out, this is much faster than digging around in the Finder to uncover a file.
The Open & Save dialog window has a lot more to it than meets the eye. You can show hidden items with Command+Shift+Period, go to any folder with path completion, and, one of my personal favorites, is to set the expanded Save dialog as default through a defaults write command.
