I am trying to build a grungey texture and in order to see it I want to use a node viewer. In this video at minute 1:28 he talks about enabling node wrangler addon and then control + shift to activate the vewier when he adds a node. THAT control + shift does not work in Blender 2.76. Is this a version difference?
Node wrangler uses Shift + Ctrl + Left-Mouse as default mapping. That means, you have to keep Shift and Ctrl keys pressed and Left-Click the node.
