Origin of "change" event

I can trigger a change event by typing text into the editor and by some methods (replaceRange, for example). Is there any way to detect how exactly was trigger change event ?

Ah, found an answer in the docs, sorry for inconvenience

Could you describe what the answer you found was and where you found it? The people of the future will thank you (see http://xkcd.com/979/).


I found that the change event has an changeObj.origin param which can be used to obtain a source of an event. And the replaceRange method has a optional param origin which can be used to pass desirable value.
