The image illustrates points 1 and 2 below.

1. Access the design space map.

Right click anywhere on the design space to access the design space map.

2. Left-click on your desired destination.

That should take you to the exact point you clicked on the map.

For your information, the design space is organized over a square perimeter around the workspace node, and each hierarchy is located on one of the cardinal directions. Depending on the Workspace you are using, different hierarchies may be in different positions.
