Try this to move more quickly through refining search results.
Google recently added a shortcut to jump back to the search box by pressing ‘/’ on your keyboard. If you are on a search results page you can refine your search by pressing ‘/’ or by clicking back into the search box.
If you use the shortcut, your text cursor will appear next to your original query. The search field then expands with suggestions for common searches related to the original term.
Do this enough times and you can turn those saved fractional seconds into real time. 😉
