The search field in the top-right corner of the iTunes window is a handy way to find content in your own library, but did you know that you can also quickly search the iTunes Store directly from this field? Simply enter your text in the search field and hold down the OPT key (Mac) or SHIFT key (Windows) when pressing RETURN and you’ll be automatically taken to a results page in the iTunes Store.

This can be particularly useful when you’re trying to determine if you already have something in your library, as you can search for it locally first, and then use the OPT/SHIFT trick to continue your search in the iTunes Store.
The best part is that this works regardless of whether you’re using the newer Live Search feature or have opted to disable Live Search and use the older style iTunes search filtering.
