The Clear All Bookmarks Action is part of the Bookmarks feature and will delete all stored bookmarks and clear the Bookmarks list in the Bookmarks dialog box.
Note:
Once you have cleared the Bookmark list in the Bookmarks dialog, there will no longer be any bookmark to move to, so the Go to Bookmark action will not work.
If you have used Multiple Bookmarks, there is no way to clear individual bookmarks from the Bookmark list.
1. Add the Clear All Bookmarks action to your trigger, as described in adding actions. There are no additional settings for this option.
2. Click on the Apply button to save your changes.
