Keyword Parameter Constants
Specify keyword values for Apple event parameters, as well as information for the AEManagerInfo function to retrieve. Some common key word values are shown here.
Overview
These constants are keyword constants for Apple event parameters. An Apple event consists of attributes (which identify the Apple event and denote its task) and, often, parameters (which contain information to be used by the target application). Taken together, the attributes of an Apple event denote the task to be performed on any data specified in the Apple event’s parameters.
Keywords are arbitrary names used by the Apple Event Manager to keep track of various descriptors. Your application cannot examine the contents of an Apple event directly. Instead, you call Apple Event Manager routines such as those described in Getting Data or Descriptors From Apple Events and Apple Event Records to request attributes and parameters by keyword.
