lets you go to search results by pressing the number of the search result instead of clicking
Its premise is simple, but it's so darn useful to people like me. I'm a keyboard- and keyboard shortcut-loving person, so this is another extension I've added to my must-install list (of extensions). I can imagine this does heaps for accessibility as well.
It works in "Google, Google News, Google Groups, Google Desktop Search, del.icio.us, and Bugzilla" at this time (most important being the Google support of course). You can see the numbers next to the links in Google search results pages, and you can open the link you want in a new tab by pressing Ctrl-1, Ctrl-2 and so on.
It also works for del.icio.us bookmark links.
A big pat on the back for Jesse.
