The navigation tree is controlled by mouse input or though the keyboard, using the arrow keys to highlight a tree node and the Enter key to select. To use keyboard input, the tree must have window focus, through a mouse click or tabbed navigation. Collapsed tree nodes are indicated by the symbol (Screenshot of navigation tree button).

If only one data type (i.e., a phase combination) is available for a given property, it is displayed as an ordinary tree node with phases and variables indicated in brackets (e.g., '[L, G(T)]' for liquid in equilibrium with gas as a function of temperature). If data are available for more than one phase combination, these sets are populated into a collapsed node. Expanding the node reveals the phase combinations available. For properties of saturated liquids and gases, the phase of the property is indicated first. A more verbose description is displayed if the mouse cursor hovers over a node.
