This is explained in https://tiddlywiki.com/#Filter%20Step The step's operator is drawn from a list of predefined keywords > <https://tiddlywiki.com/#Filter%20Operators>, which can be extended by > plugins. > Any unrecognised operator is treated as if it was the suffix to the field > <https://tiddlywiki.com/#field%20Operator> operator. > If a step's operator is omitted altogether, it defaults to title. Thus, [[text here]] *is* a filter run containing one filter step that is equivalent to [title[text here]]. Note that you can also specify a filter run that defines literal text values by using quotes, as described in https://tiddlywiki.com/#Filter%20Run The lower three options in the diagram match syntax like HelloThere, > "HelloThere", 'HelloThere' and "Filter Operators". > They are short for [title[...]]. > > The quoted options exist to support titles that contain square brackets, > as in "An [[[[Unusual]]]] Tiddler". > -e -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
