Whatever we might wish for, "objects" in and of itself does not exist in LC. It is just a mental construct, a remnant of HC days. I think that way, too, but also know that:
You cannot: "answer the number of objects." though you surely can: "answer the number of controls" I doubt the team would think this very important.

Object? If 'Object' is a reserved word, then why is the Dictionary "we all know and love" full of 'objects': errorObject focusedObject menuObject objectSelectionEnded objectSelectionStarted selectedObjectChanged selectedObject selectedObjects selObj selObjs ? Looking up 'focusedObject' one can read: "Returns the currently focused control" So there is no question of 'reserved words'; there is a simple case of a state of BAD confusion that needs to be sorted out, 2 words being used for one thing, or, rather one set of things: either: 1. Dump the word 'object' and only use 'control', or 2. Dump the word 'control' and only use 'object'. Personally I prefer #2. This is an "issue" [ a.k.a. 'fudge' ] that has been left unfixed for far, far too long. Presumably (?) this is something that can be sorted out pretty quickly using search-and-replace. Richmond.
