If you have a hidden hate for your keyboard’s companion, you know that mouse sitting over there, mocking you with its two buttons and scroll wheel of humility then you might want to look into NumberFox. This addon for Firefox will allow you to navigate links, selections, search boxes and more by typing in the corresponding number.
When NumberFox is turned on, the page is filled with numbers corresponding with the links on the page. To choose a link, all you have to do is enter the number into the NumberFox box (in the picture, seen right above the Google logo) and your off to surfing through cyber space. You can also use the up and down keys to cycle through the available links for another way to navigate through your clicking choices.
If the mouse is on your bad list, or you need an alternative this extension is a good way to go.
