Have difficulty to follow video around minutes 7. When you duplicate Glossy BSDF, then shift click you do something like Crl Ctrl O which causes to do someyhing with outgoing links, but for me always calls Open file dialog. Then with duplicated Glossy BSDF you do Shift S ( switch type node to Diffuse BSDF) which does not work for me. Can you suggest some bypasses to those key short cuts ( how to achieve the same through menu etc)?
