From the authors of <a href="https://wordpress.org/extend/plugins/wp-typography/" rel="ugc">wp-Typography</a> comes wp-TrackbackPopup.
In WordPress the default trackback link behavior causes persistent user confusion. Knowledgeable users right-click on the link and copy the link location. But the vast majority of users click the link — expecting to copy the link from the browser’s location bar — only to be redirected back to the very page they were on. The standard implementation does not provide the expected result.
wp-​​TrackbackPopup resolves this issue. It uses unob­tru­sive JavaScript to create a popup win­dow when a user clicks the track­back link. The popup window pro­vides a text ver­sion of the track­back URL for easy copy­ing and pasting. 
The popup window may be styled to match your existing theme.
