Logitech on Thursday announced new mice that it claims will ease web searches and navigation of content on a PC. The wireless MX Revolution and VX Revolution laser mice include an automatic web search button, and a wheel that can navigate through hundreds of pages in seconds, according to the company.

After flicking the MicroGear Precision Scroll Wheel, the wheel spins continuously for seven seconds, scrolling down hundreds of pages in a website, spreadsheet or word processing document, said Kate Brinks, a Logitech spokeswoman.

The free-spinning wheel makes it easier for users to navigate through long documents or data lists. "Even in a three-page document, [the mouse] reduces the repetitive motion of scrolling down. I use it a lot in my email inbox," Brinks said. The wheel can switch between the free-spin and the conventional scroll mode.

Located under the scroll wheel is the One-Touch Search button, which brings up web search results for a highlighted word or phrase with just a single click. After highlighting a term in a spreadsheet or document, clicking the search button opens a Web browser with Yahoo, Google or Yahoo LiveWords search results for the term. Logitech's SetPoint software needs to be installed for this button to work, Brinks said. Users can highlight terms for web search in any software.
