Each input title is processed in turn, and is ignored if it does not denote a data tiddler. The sorted list of property names is retrieved from the data tiddler and then dominantly appended to the operator's output.

Note that behind the scenes, the name/value pairs in a dictionary tiddler are represented as a JSON object. JSON objects do not maintain a guaranteed ordering and so we cannot reliably retain the ordering of the data in the file.

Where the content of a tiddler is in JSON format with an array as its root, the indexes operator retrieves a selection of integer indices instead.
