Native RSS reader which allows to set explizit the status of an article I am looking for a native RSS reader for Mac OS which allows me to mark an article as read or unread explicitly by a short cut. All RSS reader I found mark an article as read immediately after viewing them. So I lose the overview which articles I have read and which not.
Thank you for your answers. After trying different web-based tools and native applications I returned to Thunderbird. Thunderbird supports RSS-Feeds as well and allows you to specify the amount of time you have to view a mail or article until it marks it as read. It also allows you to disable this at all and to mark articles manually as read.
