The tm-cancel-tiddler message abandons the changes in a draft tiddler. It requires the following properties on the event object:
| Name | Description |
|---|---|
| param | Title of the tiddler that is being cancelled out of edit mode |
| tiddlerTitle | Fallback title that is used if param isn't specified (automatically set by the ButtonWidget) |
The cancel tiddler message is usually generated with the ButtonWidget and is handled by the NavigatorWidget.
