Detect Keypress event in TinyMCE Text Area

Question

I already successfully embedded a TinyMCE text editor in a text area in Drupal 7 Form API. I tried pasting the code below in my javascript code, with no luck.

tinyMCE.init({         
    setup : function(ed) {
        ed.onKeyPress.add(function(ed, e) {
            console.debug('Key press event: ' + e.keyCode);
        });
    }
});

There's no errors but only warning, everytime I type on the textarea:

'KeyboardEvent.keyLocation' is deprecated. Please use 'KeyboardEvent.location' instead. 

How will I fix the warning?

Read this link: https://www.drupal.org/node/1714068

Paste the code below in your .module file.

/**
* Implements hook_wysiwyg_editor_settings_alter().
*/
function MODULENAME_wysiwyg_editor_settings_alter(&$settings, $context){    
     if($context['profile']->editor == 'tinymce') {          
         drupal_add_js(drupal_get_path('module', 'MODULENAME') . '/MODULENAME_tinymce_callbacks.js');
         $settings['setup'] = 'MODULENAME_tinymce_setup_callback';           
     }
}

In MODULENAME_tinymce_callbacks.js

 function MODULENAME_tinymce_setup_callback(ed){ 
     var range = 0;
     ed.onEvent.add(function (ed, e) {
         range = ed.selection.getRng().startOffset;  
         console.log(range);
     });
 }

The cursor position will then be log in the console of the browser.
