Use nodes in a graph.
Nodes are the fundamental building blocks of a graph. You can select, delete, cut, copy, and paste nodes in the Graph window. You can also collapse and expand nodes for better organization, frame a node to center it in the Graph window, remove wires between nodes, and disable nodes.
This page covers information about how to manage nodes only. For information on how to create nodes, refer to Implement nodes for your graph tool. For information on node types and node anatomy, refer to About nodes.
To select multiple nodes simultaneously, use one of the following methods:
Tip: If you drag an element close to the edge of the Graph window, the canvas automatically pans. To zoom in and out, use the mouse scroll wheel.
To delete a node, right-click the node, and select Delete.
To delete multiple nodes at a time, hold down Alt+Shift (macOS: Cmd+Shift), and drag to draw a custom selection path. This deletes any nodes intersected by this path.
You can cut, copy, and paste nodes. To do so, right-click on a node, and select the action. Alternatively, use the keyboard shortcut.
To collapse or expand a node, use one of the following methods:
To center the node in the Graph window, right-click the node, and select Frame selection.
To disable a node or nodes, right-click the selected nodes, and select Disable nodes.
To remove wires from all nodes in a selected area, right-click the selected nodes, and select Disconnect all wires.
