When using Confluence as documentation system with a lot of anchor tags per article, it would be practical to have the anchors marked with a small symbol next to the text (e.g. on the left margin) including a function that copies the whole link (URL + anchor tag) to the clipboard (or sth. similar).

Normally, a requestor (reader) only wants to read the text part that describes his/her question or answer on a problem. In this case it would be easy to send him/her the complete link via email instead of looking in the wiki code via the edit function or searching for the link in the browser information.
(With our customers and interested parties it happens quite often that we have to send them a link with anchor describing their problem or question in our software documentation)

Two aspects can be additionally considered:

• switching on/off by space because this function makes only sense when a lot of anchor tags are used and links are mailed to interested people
• deciding to use either tiny or full links via config switch
