File used by macOS applications that include AppleScript support; stores a property list that specifies a mapping between developer-defined classes and the underlying Apple event codes; used with a .SCRIPTTERMINOLOGY file that contains valid AppleScript syntax.

Script Suite and Script Terminology files allow developers to define their own AppleScript language syntax to accomplish whatever tasks are required by their application. The script terminology often uses plain English commands that map to classes, which themselves map to Apple event codes. NOTE: If you change the .scriptsuite file extension to .txt, you can view the file in a plain text editor, such as Apple TextEdit.
