You create a RetargetAction. You add it to the menu. In your editor
you create an Action with the same ID. You register it (somewhere).
When menu item is triggered it will trigger your editors action, that
editors action should create the appropriate request and pass it into
the current selection which should be an editpart.

Check the GEF examples for full example.
