Unfortunately the default out-of-the-box action is still set to look everywhere on your Mac. But don't worry, it's easy to change. 1. Make sure Finder is your active app (either click on the Finder icon in the dock, click the desktop or a visible Finder window, or cmd-Tab to switch to the Finder). 2. Choose Preferences in the Finder menu. Or you can just use the Command-comma key combo to invoke Preferences. 3. In Finder Preferences, click on the Advanced tab. 4. Choose your desired search scope from the drop-down menu under the heading "When performing a search." 5. Close the Preferences and enjoy a search or two. That's it. Just one example of the many little changes in Snow Leopard that make life with the OS easier and more efficient. I hope you find what you're looking for!

One of the most annoying things about Leopard was that when I search within a folder the default was actually "This Mac"...not helpful. Now you can force it to be the Current Folder, but it isn't the default setting...
