Within the ''action'' string of the DroppableWidget, the <<.def actionTiddler>> [[variable|Variables]] contains the title of the tiddler being dropped.
The variable `actionTiddler` is used in subtly different ways by different widgets:
* Within the ''actions'' string of the DroppableWidget, the <<.def actionTiddler>> [[variable|Variables]] contains the title of the tiddler being dropped.
* Within the ''startactions'' and ''endactions'' string of the DroppableWidget, the <<.def actionTiddler>> [[variable|Variables]] contains a quoted [[Title List]] of all of the titles being dragged.
