SUMMARY There is no way to delete bookmarks from Bookmarks menu since a context menu doesn't appear. STEPS TO REPRODUCE 1. Run KHelpCenter, open any manual. 2. Add a bookmark if none created yet. 3. Right-click on any bookmark in the Bookmarks menu. OBSERVED RESULT A program behaves like a left-click was done: it opens a manual which the bookmark points to. EXPECTED RESULT A context menu of bookmark would be appeared. KHelpCenter manual says: "Use the action Delete Bookmark in the context menu of an item to remove it from the menu".
