To include a single place, junction, or segment in the permalink, click on it before using the permalink icon. To include several segments, use ctrl+click (MAC: ⌘ Command+click).
Be aware that editors cannot see Update Requests (URs) outside their editing area. If you want to discuss a UR with someone who cannot edit in your area, a screenshot of the open UR uploaded to an image-sharing website will be a useful supplement to your permalink.
