Computer mice are great and all, but sometimes you'd rather not have to deal with them — say, when you're using an uncomfortable touchpad on a laptop. Chrome Extension KeyboardNavigation helps you browse the web while keeping mouse clicking to a minimum.
Once installed, you can activate the extension by hitting Alt+G on your keyboard — this will put a number next to every link on the page. Typing in one of the numbers will take you to the linked page as if you clicked on it, and you can toggle whether to open up links in a new foreground, background, or the same tab by pressing b or g. When you want to go ahead and read the page, just hit Alt+G again to hide the numbers (as the page can get pretty cluttered pretty quickly on sites with lots of links).
KeyboardNavigation is a free download, and works with the Dev version of Chrome for Windows or the Linux beta. Firefox users, check out similar extensions like LoL.
