Question

Answer 1

Pass an onChange option to CodeMirror which looks something like this:

onChange: function (cm) {
   mySecondTextArea.value = cm.getValue();
}

Edited to note: Since CodeMirror version 2.0, you don't pass an onChange option anymore to register a change handler, but call instance.on("change", function(cm, change) { ... }) instead. http://codemirror.net/doc/manual.html#event_change
