Examples

<$button>
<$action-sendmessage $message="tm-modal" $param="SampleWizard"/>
<$action-sendmessage $message="tm-notify" $param="SampleNotification"/>
<$action-sendmessage $message="tm-new-tiddler" title="This is newly created tiddler" tags="OneTag [[Another Tag]]" text=<<now "Today is DDth, MMM YYYY">>/>
Click me!
</$button>
