The current tiddler provides the context in which several aspects of WikiText are interpreted.

For example, {{!!title}} denotes the value of the title field of whatever the current tiddler happens to be. This technique can be used to create general-purpose template tiddlers.

The title of the current tiddler can always be found in the currentTiddler variable.

The two most common ways in which the current tiddler is changed are:

• the $tiddler widget
• the $list widget (when its variable attribute is not overridden)

The current tiddler is therefore often not the same as the tiddler that is being viewed or edited.
