can you command+click an element and be brought to its source?

Are findUsages and referenceContributor enough to make source resolution work? Annotator or other extensions aren't required?

A referenceContributor should be enough for source resolution, but findUsages requires one to work to function properly

Thanks a lot, it turns out that

getReferences

should be overridden in any of the elements, and this is not mentioned in tutorial at all.
