Linking with a related-links Element in DITA

To create a list of related links within the topic you are writing (as opposed to specifying relationships externally with a relationship table):

Open the topic in Author mode in which you want the link to occur.
Select one of the related link actions from the Link drop-down list that is available on the DITA toolbar. You can choose between the following types of related links:
- Related Link to Topic... - Opens an Insert Reference dialog box that allows you to select a reference.
- Related Link to File... - Opens an Input URL dialog box that allows you to select a file.
- Related Link to Web Page... - Opens an Input URL dialog box that allows you to select a web link.

This creates a related links section at the bottom of your topic. DITA provides the linklist and linkpool elements to help you refine how your links are created and processed. See the DITA documentation for details.
