When you ask Script Debugger to work with an application, Script Debugger remembers this fact and puts the application in a known applications list. You can open a known application’s dictionary quickly:

• Choose File > Open Dictionary. In the hierarchical menu, you’ll see a set of menu items entitled “Known Applications”. Choose an application to open its dictionary.
• Choose Window > Inspectors > Known Applications if necessary, to show the Known Applications inspector. In the inspector window, double-click an application’s listing (or select it and click the Dictionary button) to open its dictionary.
