Discussion
The Apple Event Manager uniquely identifies the various parts
of an Apple event by means of keywords associated with corresponding
descriptors. Keywords are arbitrary names, stored as four-character
codes of type AEKeyword
.
A keyword combined with a descriptor forms a keyword-specified descriptor,
which is defined by a data structure of type AERemote
.
The Apple Event Manager also uses keywords for Apple event attributes. Keyword constants used by the Apple Event Manager are defined in Keyword Attribute Constants and Keyword Parameter Constants.
