The shortcut is: “Ctrl” + “T”
If you use it whilst having an Image texture node selected, it will create both Texture Coordinate and Mapping nodes and it will connect them to your selected texture node.
If you use it whilst having an Shader node (diffuse BSDF, Principled BSDF, etc…), it will also add an Image Texture Node to the two other ones.
This shortcut is part of the Node Wrangler addon.
