Regardless of where you are in the iTunes store, when you enter some text and use the search box in the upper right corner of the iTunes window, you'll get a page displaying possibilities for every part of the store where iTunes found a match. The Power Search column on the left lets you focus the results on particular sections within the store--Music, Movies, TV Shows, Apps, and so on--and move among them. Clicking Power Search at the top produces a set of categories relevant to the media type you're viewing--Actor or Director/Producer in the Movies category, for instance--plus a pop-up menu to the left that lets you switch to other media types. You can also go directly to Power Search via the Quick Links section on the main iTunes Store page.
