The Source Browser shows all the objects in your application in an expandable hierarchy. It provides a view of the structure of the application and a quick way to open any script in the Source view.
To open a script from the Source Browser:
Double-click the object that the script belongs to or click the plus sign next to the object to expand it.
Do one of the following:
Double-click the script
Select the script and select Open Source from the pop-up menu
Drag the script onto a Source view
When you double-click or select Open Source, a new Source view opens if there was none open. If several Source views are open, the script displays in the view that was used last.
