You can incorporate the content of one tiddler within another using the transclusion notation:

* `{{MyTiddler}}` transcludes a single tiddler
* `{{MyTiddler||TemplateTitle}}` displays the tiddler through a specified [[TemplateTiddler|TemplateTiddlers]]
* `{{||TemplateTitle}}` displays the specified template tiddler without altering the [[current tiddler|WidgetVariable: currentTiddler]]

You can also use a TextReference instead of a tiddler title:

* `{{MyTiddler!!field}}` transcludes a specified field of a tiddler
* `{{!!field}}` transcludes a specified field of the current tiddler
* `{{MyTiddler##index}}` transcludes a specified indexed property of a [[DataTiddler|DataTiddlers]]
* `{{##index}}` transcludes a specified indexed property of the current [[DataTiddler|DataTiddlers]]

A similar syntax can be used to transclude a list of tiddlers matching a specified [[TiddlerFilter|TiddlerFilters]]:

```
{{{ [tag[mechanism]] }}}
{{{ [tag[mechanism]] ||TemplateTitle}}}
```
