Merging Nodes

You can merge any number of selected nodes in the Node Graph tab either through the tab's Edit menu or the available keyboard shortcut. Merging selected nodes creates a Merge node that links up the selected nodes' outputs to the inputs of the Merge node. A Merge node with a single input is effectively a no-Op node.

To merge selected nodes, either press M when in the Node Graph tab or select Edit > Merge Selected Nodes from the Node Graph tab's menu bar.
