BB008 CTRL+ALT Gem in Node Wrangler

Blender's Node Wrangler is full of surprises - while making a large 3D stereoscopic tutorial, I stumbled on to altering multiple Nodes simultaneously. I thought you'd like the trick to save time.
I completely botched the stereoscope part but at least I learned this stuff! So this is the fastest video I ever hope to make - no intro, no outro, just one (two, really) little tricks.
