Mouseless Browsing (MLB) is a Firefox-Extension which enables you - as the name implies - to browse the Internet almost without using the mouse. The basic principle is to add small boxes with unique ids behind every link and/or form element. You just have to type in the id and press enter (there is also an automatic mode available) to trigger the appropriate action i.e. following a link, pressing a button or selecting a textfield.
I found from my experience this extension works to our advantage on a desktop rather than on a notebook because on a notebook you would have to move your fingers up at the top to reach out for the number keys.
I have the settings as below:
If you don’t want the id numbers to show up by default, check Show ids only on demand. To toggle the effect of this extension on and off, you can use press the decimal which is the default. This default can be changed in the Keys tab.
You can read more about it and install from http://www.rudolf-noe.de/MouselessBrowsing.htm.
If you don’t want the full fledged MLB, you can use Search Keys extension which will display numbers in small boxes next to only search results from Google, Yahoo etc. and at del.icio.us. Pressing the number will take you to that corresponding URL. Hold Alt (Windows/Mac) or Ctrl (Linux) to open results in new tabs, or Shift to open results in new windows.
The next extension we are going to look at is BetterSearch. It adds small buttons next to search results so you can easily open them in new tab, preview the content right in that search results page. It also other features but I found them to be not so helpful in increasing productivity.
