 **Hidden tags:** Tags starting with a dot `.` (example `.secret`) are private. They can only be seen and searched when logged in.
 
-Alternatively you can use the `Tag cloud` to discover all tags and click on any of them to display related links.
+### Tag cloud
 
-To search for links that are not tagged, enter `""` in the tag search field.
+The `Tag cloud` page diplays a "cloud" view of all tags in your Shaarli.
+
+ * The most frequently used tags are displayed with a bigger font size.
+ * When sorting by `Most used` or `Alphabetical`, tags are displayed as a _list_, along with counters and edit/delete buttons for each tag.
+ * Clicking on any tag will display a list of all Shaares matching this tag.
+ * Clicking on the counter next to a tag `example`, will filter the tag cloud to only display tags found in Shaares tagged `example`. Repeat this any number of times to further filter the tag cloud. Click `List all links with those tags` to display Shaares matching your current tag filter.
 
 ## Filtering RSS feeds/Picture wall
 
 RSS feeds can also be restricted to only return items matching a text/tag search: see [RSS feeds](RSS-feeds).
+
+## Filter buttons
+
+Filter buttons can be found at the top left of the link list. They allow you to apply different filters to the list:
+
+ * **Private links:** When this toggle button is enabled, only shaares set to `private` will be shown.
+ * **Untagged links:** When the this toggle button is enabled (top left of the link list), only shaares _without any tags_ will be shown in the link list.
+ 
+Filter buttons are only available when logged in.
