Google Reader provides stats on the % Read for each feed. The problem is that most of these(for me at least) are at 100% so are not very useful.
I use the 'j' shortcut key to flick through the unread items but this automatically marks the item as read even if I didn't actually read it.
How do I mark an item as 'not new' so that the stats provide an accurate view of my feed reading habits?
