Marry Christmas!
I investigate how to run CKEditor in maximized mode (IMHO, мore convenient: the toolbar is fixed at the top of the page) and want to share search results.
So, just add this code to Global Administration: WYSIWYG Editor ADVANCED CONFIGURATION field and save it:
CKEDITOR.on('instanceReady',
function( evt )
{
var editor = evt.editor;
editor.execCommand('maximize');
});
