Open in Terminal keyboard shortcut not configurable on Ubuntu 18.04.2 LTS

[Anindya Das]

I tried to enable shortcut for "Open in terminal" that is used to open terminal in a particular folder that I am currently in. Although the option appears on right click, however I could not configure a keyboard shortcut for the same.

1. I have tried installing nautilus-open-terminal package and it says package not found.
2. I have tried installing nautilus-extension-gnome-terminal and it says:
"nautilus-extension-gnome-terminal is already the newest version (3.28.2-1ubuntu1~18.04.1).
0 upgraded, 0 newly installed, 0 to remove and 41 not upgraded."

None of the methods work!

Codename: bionic

A fix or solution for this would be great!
