Feature Request: Provide keyboard shortcut to copy a value

[vdobler]

Copying values in interactive mode with the mouse is possible but a bit cumbersome.
It would be very convenient if (leave) values could be copied to the clipboard with a keystroke. E.g

"foo": "some value"
‾‾‾‾‾    

With the ‾‾‾ marking the highlighted element, a keypress of e.g. y or Ctrl-c could copy
some value to the clip board.

Rational: I often use fx to look up some value in a JSON, e.g. for debugging purpose and extracting values during interactive use is cumbersome.

(For compound values (arrays, objects) this might be not implemented or copy the whole compound thing; not really a use case for me.)
