Application Development Software

Our customers are using the Web Form Editor for some WYSIWYG changes. The form has too many options and they would like to limit what the users can do. We have attempted to make changes to the following files to customize the CKEditor for Web Form Editor and cannot see our changes reflected after saving/restarting Content Server.
Instance\weblayout\webform\ckeditor\config.js
Instance\weblayout\resources\wcm\3rdparty\fckeditor\fckconfig.js
Instance\custom\FCKEditor\webform\ckeditor\config.js

To test a simple change we tried adding the following to change the toolbar options.
CKEDITOR.editorConfig = function( config )
{
config.toolbar = 'MyToolbar';

config.toolbar_MyToolbar =
[
['NewPage','Preview'],
['Cut','Copy','Paste','PasteText','PasteFromWord','-','Scayt'],
['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'],
['Image','Table','HorizontalRule','Smiley','SpecialChar','PageBreak'],
'/',
['Styles','Format'],
['Bold','Italic','Strike'],
['NumberedList','BulletedList','-','Outdent','Indent'],
['Link','Unlink','Anchor'],
['Maximize','-','About']
];
};

There isn't much standard documentation on this out of the box feature and I've searched Oracle Support with no luck.
