Expert Mode

In Expert Mode you create actions by entering ActionScript into the text box on the right side of the panel or by selecting actions from the Toolbox list on the left. You edit actions, enter parameters for actions, or delete actions directly in the text box, much like creating script in a text editor.

Expert Mode lets advanced ActionScript users edit their scripts with a text editor, as they would JavaScript or VBScript. Expert Mode differs from Normal Mode in these ways:

Selecting an item using the Add (+) button or Toolbox list inserts the item in the text-editing area.
No parameter fields appear.
In the button panel, only the Add (+) button works.
The Up and Down Arrow buttons remain inactive.
