I don't know if anyone else is using Gleebox, but I've absolutely fallen in love with it. It's a keyboard navigation tool, available for Chrome (now my primary browser) and Firefox.
I get a tiny feeling of euphoria every time I catch myself with my hand halfway to the mouse, stop myself and hit 'g' instead.
It's ridiculously easy to add jquery selector-based scrapers to make the "esp" mode compatible with most websites. The one I use for lj is:
wererogue.livejournal.com : a[href*=cutid],tr>td>div>a
YMMV - The nested tags will depend in part if you have more styling on your links, headers etc. If lj used style sheets and classes, it'd be more predictable, but this works for me.
