Move Between Categories in the Spotlight With a Keyboard Shortcut
Spotlight search is great, but some searches contain many different categories of documents. OS X Daily notes that you can easily switch between these different categories using a keyboard shortcut.
Start by searching for Spotlight (Command + Space) and enter your search term. After the results are displayed, hold down the Command key and click the up and down arrows to navigate between each category. This makes it pretty darn easy to use.
