For projects with large ORM configurations, it would be convenient to have a way to quickly navigate to an entity by name. (Similar to Ctrl-N for Java classes)
Ctrl-N is not always useful here: entities can have an explicit name, and a Java class can be mapped more that once (as different entities).
There is already a request to make Ctrl-Shift-Alt-N extensible (IDEADEV-13602): this might be a candidate for that functionality.
