Proper syntax for CKEDITOR.ENTER_BR

This does not appear to be working in the config.js file:


CKEDITOR.editorConfig = function( config )
{
// Define changes to default configuration here. For example:
// config.language = 'fr';
// config.uiColor = '#AADC6E';

config.enterMode = CKEDITOR.ENTER_BR; // <----------------<<<
config.width = '700px';
config.height = '125px';
