We have just released version 0.9.41, which contains a preliminary version of the Usages tool. To upgrade, you must already have updated to the Eclipse 3.2 version, and subscribe to the new update site (as detailed in https://sourceforge.net/forum/message.php?msg_id=3971357). To use this feature: select any element in the editor, right-click, and choose 'Show Usages'.
You will see a table with a list of places where the model is used. Double-clicking on any of the rows will take you to the relevant model.
