Feature Request: allow copying keys #41
Description
Often I'm working with international data, I import it as a JSON blob, then view it using the json-viewer. (Which has become an important part of my workflow now).
When I find the field I want and need to process it, I need to copy the key to my code, but there's no way to simply highlight the key and select it.
Related to #40 but has to do with keys, not values.
