Many valuable, valid AppleScript terms (e.g., "AXRaise") are not documented in the AppleScript command, statement, value, handler, event, object, keyword, and class references, etc., that are published on developer.apple.com (e.g., at https://developer.apple.com/library/archive/documentation/AppleScript/Conceptual/AppleScriptLangGuide/introduction/ASLR_intro.html#//apple_ref/doc/uid/TP40000983).
Has Apple (or anyone else) ever compiled a complete, comprehensive dictionary or list of all of the terms that are available and valid for use within AppleScript?
