In this video I show you a few simple keyboard shortcuts for connecting nodes and moving nodes in your Nuke script. Knowing some of these simple shortcuts can really speed up your compositing in Nuke
With two nodes selected, pressing Y will connect the input of which ever node was selected first, to the other node. Shift+Y will connect the input of the second node selected to the first.
CTR+SHIFT+X (⌘+SHIFT+X on a Mac) will disconnect any selected nodes from the rest of your script.
CTR/⌘ + ↑ or CTR/⌘ + ↓ will move the selected node up or down the branch, leapfrogging other nodes above or below it.
Holding shift while you create a new node will automatically put the new node on a new branch of your script.
Pressing Shift+X will swap the inputs of the selected node, eg switch A and B.
