Google has launched the latest version of its toolbar, the Toolbar 6, for Internet Explorer. Google Toolbar 6 for Internet Explorer has the Quick Search Box (QSB) feature that provides search functionality outside of the browser.
Quick Search Box lets you easily search both your computer and the Web from a slick-looking search box that comes up only when you need it.
Clicking the Google button on your computer taskbar will bring you a search box. You can press Ctrl + spacebar as a shortcut. Type the search keyword to find Programs on your computer, Search results on Google and Websites. As you type, the search box will show you matching programs.
