The Object Behaviors dialog
The Object Behaviors dialog lists all the behaviors an object type has. It can be opened from the Properties Bar while the object's properties are showing, or from right-clicking the object in the Project Bar or Object Bar and selecting Behaviors.... For documentation on individual behaviors, see the Behavior Reference section of the manual.
Behaviors can be added with the toolbar at the top or by right-clicking and selecting Add behavior. This opens the Add Behavior dialog. The toolbar and right-click menu also allow you to rename (F2) or delete (Del) behaviors. The behavior is referred to in the event system by its name.
Behaviors can be reordered by using the Up and Down buttons on the toolbar, or by dragging and dropping them. The order of behaviors is just for organisation - it does not affect how they actually work.
