The major goal of this tool is to make it where you can browse through the Web using the number pad to navigate through links. You would hit “1″ to go to the first link, “2″ to go to the second, and so on and so forth. Here is a little more on the process from the extension developer.

You can configure to use the numpad exclusively for Mouseless Browsing. In that mode you can trigger actions even the focus is on a textfield or selectbox. The output is suppressed. If you not use the exclusive mode then triggering actions by typing ids don’t work if the focus is on a textfield or a selectbox. Entering the id while holding the CTRL-Key triggers the action in any case. You can toggle between the two modes by pressing the num-key twice within 1 sec.

It might take a little ‘bit of time to configure the extension to your liking but once you do I could see anybody using this as an alternative way to browse around any web page. Also be sure to check out the official site for Mouseless Browsing to get some more configuration help and advice.
