R can reference either a field or a property. See TextReference for the syntax.

  • If neither is specified, the list field is used by default. So [list[T]] outputs the titles listed in the list field of tiddler T.
  • If R consists of only a field or a property, the tiddler part of the reference defaults to the current tiddler. So [list[!!tags]] outputs the titles listed in the tags field of the current tiddler.
