We are accustomed to our input devices; the keyboard and mouse. Some prefer to use the mouse as much as possible while others prefer not to deter from their keyboard. Google is experimenting with their search result interface to accommodate web surfers who favor the keyboard. These kinds of keyboard shortcuts should have no impact on search engine optimization.
The experimental system assigns common actions to certain keys, as outlined below. The common shortcuts will be for selecting the next result, selecting the previous result, and opening a result.
J selects next result K selects previous result O opens selected result Enter opens selected result / puts cursor in search box Esc removes cursor from search box
Most will continue to use the mouse during Google searches. They may maintain the mouse provides an easier see-point-click selection method while the keyboard allows only an incremental up-down selection method.
The keyboard cowboys embracing the new technique during Google searches will undoubtedly find a smooth flow between their searches and their destination without having to defer to the mouse.
