Imagine you had a Chrome/Firefox/IE? extension that can use the same keys to handle the same basic actions throughout every web page you visit.
Lets assume your are visiting google.com and search for Js Slider
. Now you want to move to the next page of results. Currently you have to click Next Page.
But what if Google implements their very own keyboard keys for their search. So they decide that if your press Ctrl+Alt+N you move to the next page. But what if Bing makes it Ctrl+Alt+P? And Yahoo makes it Cmd+Alt+N?
