CKEditor – adding Advisory Title for <a> element

Question

I have problem with CKEditor. I tried creating <a href="#"></a> element in CKEditor with advisory title, but I can't do it.

I set this option in modal, tab advenced.

Do you have any idea how to fix this?

This my CKEditor configuration:

CKEDITOR.editorConfig = function( config )
{
    config.toolbar = 'Full_Theme';
    config.toolbar_Full_Theme =
        [
            ['Format','Font','FontSize'],['TextColor'],['BGColor'],
            ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
            ['Bold','Italic','Strike'],
            ['NumberedList','BulletedList'],
            ['Outdent','Indent'],
            '/',
            ['Link','Unlink'],
            ['Image'],['Table'],['HorizontalRule'],['VideoImage'],['Source'],['Maximize'],
            ['Undo','Redo'],
        ];

    config.toolbar = 'Simple_Theme';
    config.toolbar_Simple_Theme =
        [
             ['Maximize'],
             ['Undo','Redo'],
             '/',*/
            ['Format','Font','FontSize'],['TextColor'],['BGColor'],
            ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
            ['Bold','Italic','Strike'],
            ['NumberedList','BulletedList'],
            ['Outdent','Indent'],
            '/',
            ['Link','Unlink'],
