You can perform various actions within a structure visualizer, as described
below.
5.4.1 Expanding Pointers
You can expand scalar pointers in a structure to generate new nodes. (You cannot
expand a pointer to a parallel variable.)
To expand a single pointer:
* With a mouse: Left-click on a button to expand the pointer. For example,
clicking on the button next to the nav field in Figure 30 changes the visualizer
as shown in Figure 31.
* From the keyboard: Use the right arrow key to expand and visit the node
pointed to by the current button. If the node is already expanded, pressing
the right arrow key simply visits the node. Use the left arrow key to visit
the parent of a selected node.

To expand all pointers in a node:
* With the mouse: Double-click or Shift-left-click on the node.
