TAB keyboard button for adding new nodes


I’m coming from Houdini and I have been using unreal for a while now and found that using the RMB only for adding new node in the material editor is very annoying.
I used to using the TAB key button for quick adding new nodes for much every node based packages like Houdini, Substance Designer, Maya and Nuke.

I don’t know if there’s ability map keyboard to this feature or not so please if there’s any let us know.
Otherwise, It will be a great addition to the Engine in the future releases.
