Over the last year or so I've become a fan of keyboard shortcuts (think Vim, Inkscape, Gmail, etc..). But I've largely stuck with mousing around in Google Reader... until now.
Lifehacker has a post with some really kickass Google Reader tips. The g+s and g+h shortcuts are time-savers, but the g+u+feedname is really really top notch.
If you're a Google Reader user, you really should check out that post.
