! Introduction

The button widget displays an HTML `<button>` element that can perform a combination of optional actions when clicked:

* Executing any ActionWidgets that are immediate children of the button widget
* Execute any integrated actions:
** Navigate to a specified tiddler
** Dispatch a user defined [[widget message|Messages]]
** Trigger a user defined [[popup|PopupMechanism]]
** Assign new text to a specified tiddler

The integrated actions are provided as a shortcut for invoking common actions. The same functionality is available via ActionWidgets, with the exception of the support for highlighting selected popups.

! Content and Attributes

The content of the `<$button>` widget is displayed within the button.
