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 5-17 changes the visualizer as shown in Figure 5-18.
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.
From the keyboard - Press the Shift key along with the right arrow key.
From the Options menu - Click on Expand. The cursor turns into a target; move the cursor to the node you are interested in and left-click.
To recursively expand all pointers from the selected node on down:
With the mouse - Triple-click or Control-left-click on the node.
From the keyboard - Press the Control key and the right arrow key.
From the Options menu - Click on Expand All. The cursor turns into a target; move the cursor to the node you are interested in and left-click.
