You can open an application’s dictionary in several different ways, depending on what you’re doing and what’s convenient.

• There are various basic ways to open any application or scripting addition’s dictionary.
• If an application is running, you can open its dictionary directly.
• If you’re editing a script that targets an application, you can open that application’s dictionary directly.
• If you’ve already worked with an application, Script Debugger remembers this fact, and you can open the dictionary from a list of previously used applications.
• If the dictionary you want to open is a special dictionary — it’s an installed scripting addition, or it’s the AppleScript Studio dictionary, or it’s the dictionary of AppleScript itself — you can open it directly.

You can open multiple windows on the same dictionary. Bring a dictionary window to the front, and choose Dictionary > Open in New Window. This makes it easy to view different pieces of information simultaneously, or to have both a dictionary and an explorer open for the same application.

Note: In some cases, opening an application’s dictionary will require the application to be running. If this is the case, and the application is not running, then when you ask to open the application’s dictionary, Script Debugger will launch the application, which may cause a delay. However, once Script Debugger has opened an application’s dictionary, it caches the dictionary. Thus, having opened such an application’s dictionary, you can now close the application and its dictionary and later open its dictionary again and this time Script Debugger will not have to launch the application.
