Put the script to your plugins directory,

copy and paste:

 ###

import CopyWithLinks

nuke.menu('Node Graph').addMenu('KirillPleshakov').addCommand('CopyWithLinks', 'CopyWithLinks.copyWithLinks()','Ctrl+Shift+v')

###

 to your menu.py

Select your node(s), hit Ctrl+Shift+v

Linked node(s) created, now you can unlink what you don't want to be linked... That's one of the points to Copy with Links instead of cloning.

If you wanna assign a different shortcut - change it at the end of the code

Another fast way to copy with links - Select node(s) - Right-Click anywhere on the Node Graph - FrameForge - CopyWithLinks

Write bugs and critics, I will make it work better!
