Rather than point and click with the mouse, these Firefox builds let users apply the Shift and Alt keys, then one of the four cursor keys, to move to a nearby link on a Web page.
Although that idea is far from new, the spin here is that the keystroke combinations take users to the next link by visual position, not its place in the HTML source code. To move to a link immediately to the right of the current link, users would press Shift-Alt-right arrow.
