#TinyMCE hotkeys

Add 'format' to initalization:
````
formats: {text_center: {selector: 'p,h1,h2,h3,h4,h5,table', classes: 'text-center'}}
````

Then add the shortcut in 'setup':
````
setup: function (ed) {
  ed.addShortcut('ctrl+alt+c', 'text_center', function(){
    ed.formatter.apply('text_center');
  });
}
````
