Jump from Window to Folder
To open another image in the same folder as a document currently open in Photoshop in Mac OS X, Command-click on the title in the document window’s title bar and select the folder from the pop-up menu that appears. This tells Photoshop to switch to the desktop and open that folder. In Windows, you can see a document’s folder path by holding the cursor over a document’s title bar until a tool tip appears.
