IntelliJ IDEA 12.1.0 Web Help
Some features described here are available in Ultimate edition only.
There is a possibility to limit view to selected dependencies only.
Note, that in contrary to Limit Scope,
only classes which produce dependencies selected are left.
In the DSM view, select the cell to explore.
Right-click the dependency and choose Explore Dependencies Between on the context menu.
The classes that produce these dependencies will be opened in a new tab within the DSM view.
