Folks: I get it. It seems an odd way to implement it, though. Anyway, a clarification in the docs would help the confusion, and the use of the word "items" in the docs is definitely confusing.
Another thing that confuses me, as a newbie, is the free interchangeable use of "handler" and "script". In my understanding, a "script" is the entire collection of handlers within an object. A handler is what comes between the "on someName" and the "end someName" or the "function someName" and the "end someName". I am still not clear on the limits of how many "scripts" in the front scripts and whether the limit applies to "scripts" or "handlers". Minor frustrations all, because i do like livecode and have been feeling very productive using it.
