I may have been slow off the mark on this but I recently discovered keyboard equivalents to browser and forward buttons. They are: Alt+[Let Arrow] for back and Alt+[Right Arrow] for forward. I may have first discovered their existence in Firefox but they seem to be more widely available than that with the same trickery working in Chrome and Internet Explorer having them too. The existence of these keyboard shortcuts might provide some pause for thought too for those web application developers who plan on disabling the Back and Forward functionality in browsers but being able to save mouse mileage with keyboard can’t be bad.
