How to override save operation - the solution

I've seen a few people ask how to override the save function so that it can be handled by javascript instead of via a form submission. I have a working solution and it's simple (though it took a while for me to figure this out)

// create the editor
var ckEditor = CKEDITOR.replace( ...etc ) 

// wait until the editor is done initializing
ckEditor.on("instanceReady",function() {

  // overwrite the default save function
  ckEditor.addCommand( "save", {
    modes : { wysiwyg:1, source:1 },
    exec : function () {

      // get the editor content
      var theData = ckEditor.getData();
      alert("insert your code here");
    }
 });
