Installation with Jquery

Hello,
I am trying to install ckeditor with jquery, but I do not understand why some things do not work.
For example, I want to use the file Config.php, therefore I like it

$(document).ready(function()
   {
      $( '#article' ).ckeditor( function() { customConfig : '/back_office/includes/editeur_texte/ckeditor/config.js' } );
   });

Then I specify the parameters in the file config.js like this.

CKEDITOR.editorConfig = function( config )
{
   config.language = 'fr';
   config.shiftEnterMode : CKEDITOR.ENTER_P;
   config.enterMode : CKEDITOR.ENTER_BR;
   config.toolbar:
         [
            ['Bold', 'Italic', '-', 'NumberedList', 'BulletedList', '-', 'Link', 'Unlink'],
            ['UIColor']
         ]
};

And here I find myself with the toolbar "full" and Js error:
SyntaxError: invalid label -> config.shiftEnterMode : CKEDITOR.ENTER_P;

In addition I would like Sev configuration toolbar.
Thank you for your help
