PhpStorm and support for ExtJS

Hello !

In the moment i work with the javascript library ExtJS.
I have added this library to my project.
I have added the library with all comments.

Now i write a little example script:
-----------------------

var test = new Ext.Window({
     title: 'my window'
});

-------------------------

The library has been commented with JavaDoc.
How can I activate the help function ?



Your sincerly

Stephan
