Spotlight has a nifty integration of keystrokes (or the Command keystroke at least). Simply perform a search and then use the Command key in combination with an arrow to move and up and down in search results based on section rather than line item. Additionally, that Command key can be used in conjunction with the Enter key so that when you open an item in the Spotlight results, it actually just displays the directory so you can then open the file in the Finder (and subsequently access other files in those directories as needed).
