-The CurrentTiddler is the current tiddler during WikiText rendering. It is usually set by the TiddlerWidget. It allows you to write references like `<$view field="title"/>` in TemplateTiddlers without explicitly specifying the tiddler that it applies to.
+The current tiddler provides an ever-changing context or background against which several features of WikiText are interpreted.
 
-The title of the current tiddler is contained in the [[WidgetVariable: currentTiddler]].
+For example, `{{!!title}}` denotes the value of the ''title'' field of whatever the current tiddler happens to be. This technique can be used in a [[TemplateTiddler|TemplateTiddlers]] to keep the template generic.
+
+The title of the current tiddler can always be found in the [[currentTiddler variable|WidgetVariable: currentTiddler]].
+
+The current tiddler is set in several ways, including by the ListWidget and the TiddlerWidget.
