If you’ve been using Google Reader for a while, you probably know about using J and K to go forwards and back through stories. Well this is what I use, along with the list view, to read a lot of stories at speed. I audition them for my attention, if they don’t grab it, I’m onto the next. There is one more shortcut though, that I like for this purpose. The humble U.
U removes the list of folders and feeds on the left-hand side of the reader, giving all of the screen space over to the actual stories themselves. I normally tend to view all, rather than view folders individually, so it lets me see more of the stories in one go to make my value judgement without having to scroll. To get the list of folders and feeds back, just tap U again.
