Tiddlers can use transclusion. This means that one tiddler sucks in and presents the content of another tiddler within itself. The basic syntax for markdown tiddlers is, on a line by itself:
{{tiddler title}}
As with WikiLinks, an @<name of tank> can be appended (outside the }})
to transclude from a different tank. If the current user cannot read from
the other tank the transclusion will not happen. If the tank name contains
spaces surround the name with [[ and ]].
When instructions wrap a word or phrase in
<and>, replace the entire phrase, including<and>with the chosen value. For example@<my tank>would become@cdent.
Transclusion is also possible in TiddlyWiki text, using macros.
