"window" is a predefined JavaScript object. See
http://w3schools.com/jsref/obj_window.asp . It has global scope so you
can access its properties everywhere. My suggestion was to save a
reference to the editor instance on the window object so that you can
access the editor later.

You should be able access the editor using window['content_editor'] in
JavaScript.

That is GWT's JavaScript Native Interface (JSNI) notation. See
http://googlewebtoolkit.blogspot.com/2008/07/getting-to-really-know-gwt-part-1-jsni.html
. Replace editorJSReference with window['content_editor'].
