I just compiled a build and tried it out. It looks like marking something as read right now just affects the dot icon next to a story with no way to filter out read stories, even after a refresh. Having different hotkeys for mark as read and unread was a little confusing. I would just have Command M toggle between the two. Then you can use the up/down arrow keys to navigate the stories and then quickly mark them. If you accidentally mark the wrong story, you don't need to find Shift to undo that.
