Drag between two connectors, or click one connector and then the other, to wire nodes together.

RMB on connector

Insert a new node before any currently connected nodes.

Y

Hold Y and drag across wires to cut (disconnect) them.

Shake node

Disconnect from any wires.

Alt + LMB on wire

Add dot.

You can also Alt-click while drawing a wire to insert a dot “on the fly”.

Pin/unpin the dot.

You can also ⌃ Ctrl + Alt-click while drawing a wire to insert a pinned dot “on the fly”.

8 while dropping node

Holding 8 temporarily disables wiring the node in if you drop the node on a wire. This lets you drop a node without worrying about accidentally rewiring it if there is an existing wire in the same area.

If you've turned off Tools ▸ Allow dropping nodes on wires, then holding 8 temporarily enables dropping a node onto a wire to wire it in.

MMB

Press MMB on a node to show the node info window while you hold the button down. This is a quick way to glance at the information in the info window.

⇧ Shift + MMB

Press ⇧ Shift + MMB on a node to show the node info window without cooking the node. This may be useful for nodes that take a long time to cook.

Alt + drag node

Create a copy of the node.

S + drag box selection

Holding S locks the drag to be a selection. This can be useful if there’s not enough “empty” space to start a box selection without hitting something else.

Laying out nodes

// Note: have to indent this so the Include below doesn’t get sucked under this heading.

Key

Description

Drag node + Space

When dragging a node, hold Space to lock the mouse pointer inside the network view. This lets you autoscroll long distances without worrying about the mouse pointer going outside the pane.

A

Hold A and drag up/left on a node to automatically lay out the upstream nodes. Drag down/right to lay out the downstream nodes. If some nodes are selected, only those nodes are moved.

⇧ Shift + A

Select the nodes to align, then hold ⇧ Shift + A and drag on the node to align to. Drag left/right to align horizontally, or up/down to align vertically.

Alt + A

Select the nodes to move, then hold Alt + A and drag left/right on a node. Drag left/right to distribute horizontally, or up/down to distribute vertically.
