The Edit Document Links window contains a list of document id numbers that are related or "linked" to a document. You can use this window to simply view the list, or you can operate on the list.
To add a new document link for a document; input a document id to which you wish to establish a link, then click the Add button.
To remove a link to a document; select the row from the Existing Document Link list window, and click the Remove button.
