I'm a little late in commenting on this, but last week Bloglines implemented hotkeys that facilitate working through a folder of feed entries. You can also use the keyboard to skip to the next feed in your queue, or skip to the next folder. Beware of that last command—"f," which skips to the next folder. Hit it by mistake and Bloglines hangs for a while (in the case of a big folder with many feeds and unread entries), then splats a tremendous amount of material onto your screen. The worst part is that every feed in that folder is instantly marked as read, and reset to the present moment. Very much a nuisance if done accidentally. I'd prefer Control+f in that case, and wouldn't mind using the Control key in all the commands.
