How to See Node Neighborhood?

[kde-baskets-user]

Hello. What's the best way to see a node neighborhood, i.e. all nodes connected to the node, regardless of direction. I have
a pretty complicated diagram and have a hard time finding all neighbors. Also what about extended neighborhood, i.e. see all nodes connected to a given one through less than MAX hops?

Thanks.

This idea is similar to #1594
A Node search dialog to find neighboring nodes (1st level, 2nd level).
or select nodes based on their colors or shape
