From the authors of wp-Typography 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.
