Coping with Windows 8 Start: Type-to-search
A major difference with Windows 8 is that results from type-to-search are visible only one category at a time, instead of showing the first three choices from each category, as is the case with Vista and Windows 7. In Windows 8, categories are listed beneath the search box. Just use the arrow keys or mouse to navigate between categories to reveal relevant results. Triggering a search from within a Metro app by pressing Win-Q will automatically have the current app used as the context for the search.
