Copy full path

[PeterKottas]

Is your feature request related to a problem? Please describe.
It would be great if you could (probably via context menu) copy the full path of the key.

Describe the solution you'd like
Imagine your son looks like this:

{
  "common": {
    "buttons": {
      "create": "Create"
     }
  }
}

I propose to add the context menu (right-click) item that would copy the path to this item to be pasted to code. In this example, it would copy the string "common.buttons.create".

The key separator should also be added to settings as part of this feature.

@PeterKottas nice one.

These days I'm not having time to implement new features, in the v3.1 I'm planning to create per-project settings, so we can define specific settings for each project independently, as the case of this feature.

Sounds good!
