Tagging enables you to assign your own keywords to items, making it easy to classify and locate articles you've previously read. To assign a tag to an item, simply click the tag icon under the article's headline to display the tag editor.
When possible, the tag editor will suggest a few tags for the article you've selected. These suggestions will improve over time as you tag more articles.
A list of your tags appears at the bottom of FeedDemon's feed bar. Selecting a tag in this list will display a newspaper containing all items with that tag.
Note: When you tag an article in a feed that's synchronized with Google Reader, that tag will also be synchronized.
