2	Node Group	Groups nodes by their category
3	Node	The node that can be dragged into the graph editor

Graph Variables

Reference Number	Option	Description
1	Add Variable	Creates a new graph variable
2	Search	Filters the current graph variables by name.
3	Variable List	List of all current graph variables
4	Variable Properties	Fields to set the properties of the selected variable.
5	Delete Variable	Deletes the selected variable.

Placing Variables

Mouse-over a variable in the list and two buttons appear for either reading or writing that variable. Drag from each button into the graph editor to place either a read or write instance of that variable for use in the graph.

Variable Search

When you mouse-over a variable in the variable list, click on the eyeglass icon to access a list of all instances of that variable in your graph. The list can be used to select specific instances used in the graph. If they are out of view, pressing the F key after selecting an instance will frame it in the view of the graph editor.

Editing Variables

Changing a variable name or datatype will update all instances of that variable in a graph. If a variable is updated to a type that is incompatible with the way its instances are used in the graph (example: from a float to a string), the existing wiring will need to be redone so the graph can function properly without errors or warnings.

Right clicking on the variable in the variable list gives you additional options to duplicate and delete the variable.

Navigation

There are a few ways to navigate the Visual Scripting graph editor:

Button	Movement	Description
Middle Mouse Button	Pan	Moves the editor view left, right, up, and down
Mouse Wheel	Zoom	Zooms toward or away from nodes in the editor

Wiring

These are the keyboard and mouse combinations to wire nodes together by connecting their ports.

Left mouse drag button - Connect wire

Dragging with LMB between two compatible ports will connect them with a wire and allow data or execution flow to progress between the two nodes. You can wire from an input to an output, or in reverse from an output to an input.

Ctrl + Left mouse button drag (on port) - Move existing wire

Holding the CTRL key on your keyboard while dragging on a port with an existing wire will allow you to move that wire to a different port on any node. The destination port must be a compatible datatype for a successful rewire. Ports with fan-in or fan-out wires will move all the wires together to the new port.

Right mouse button (on wire) - Disconnect

Clicking the right mouse button on a wire will disconnect the wire.

Right mouse button (on port) - Context sensitive menu

Clicking the right mouse button on a port will open a menu that allows setting ports from existing variables, writing to a new variable, or promoting a port to a constant. On certain types of input ports, the context menu will allow you to set the datatype manually instead of requiring an input to be wired to the port.
