title: TextReference tags: concepts A TextReference identifies a chunk of text from a tiddler that can be retrieved or modified depending on the context. TextReferences are made up of several parts, most of which can be optional: * `` - the text [[field|TiddlerFields]] of the specified tiddler * `!!` - a tiddler metadata [[field|TiddlerFields]] (eg, `modified`, `modifier`, `type` etc) * `!!` - a metadata [[field|TiddlerFields]] of the current tiddler * `##` - extracts a named property from DataTiddlers
