The download file message causes the current saver module to prompt the user to download the result of parsing a specified template tiddler as a file. It requires the following properties on the `event` object:
|!Name |!Description |
|param |Title of a tiddler to use as a template for the new tiddler |
The download file message is usually generated with the ButtonWidget.
The download file message is handled by the TiddlyWiki core SyncMechanism which invokes the current [[SaverModule|SaverModules]].
