Context menu of a post provides various actions. For example, you can delete that post or move into another place inside the Newzie.
Since posts are shown in many places inside the Newzie environment, there are many place from where you can reach context menu of any shown post.
Note that when you open subscriptions to see their retrieved posts, Newzie lists those posts either in traditional way that is the same as your email client lists your emails, or inside html-based webpage like pages.
When posts are listed in html-based pages, then each post has a ( ) icon, which can only be seen when you move your mouse cursor over the post. Just click that icon to get the context menu for that focused post.
When posts are listed in old fashion, just make a right click on that post to get its context menu.
