 Copy a string to the clipboard. 
 Only works as a result of user action (i.e. inside a `click` event listener).

 Create a new `<textarea>` element, fill it with the supplied data and add it to the HTML document.
 Use `Selection.getRangeAt()`to store the selected range (if any).
 Use `document.execCommand('copy')` to copy to the clipboard.

 Check if `keys` is non-empty and use `Array.prototype.every()` to sequentially check its keys to internal depth of the object, `obj`. 
 Use `Object.prototype.hasOwnProperty()` to check if `obj` does not have the current key or is not an object, stop propagation and return `false`.
 Otherwise assign the key's value to `obj` to use on the next iteration.
