	Inputs. Used to set values or trigger events on the node. For more information, see Ports.
	Outputs. Used to supply a value or event generated by the node. For more information, see Ports.
	Editable value. Used to manually set the value for an input, output or parameter. If the property is associated with an input port, you lose the ability to manually set a value if you create a connection on that port.

The colors shown in this documentation may be different to the colors that you see locally. {% endhint %} ## Adding nodes to a graph * To add a node, right click in the AFX canvas, and then select a node from the menu.
