You can select all the nodes which depend on a selected group of nodes.
To select reachable nodes along incoming arcs:
The any choice in the palette matches any arc type.
Since composite arcs may contain (elided) non-composite arcs of the specified arc type, the search may pass through these composite arcs to select the matching nodes. The composite arc type choice matches only composite arcs.
Nodes that are reachable along incoming arcs of the specified type to the starting nodes become selected.
The reachable nodes are added to the previously selected starting nodes (rather than replacing them).
