Make Task Flow Inline Popup to close on "esc" button

Make Task Flow Inline Popup to close on "esc" button

I am using JDeveloper 11.1.2.3.0 I have created a task flow (with jsf
pages not jsff) which I call on button click. I have chosen to display it
as Inline Popup and everything works fine. It is just that it does not act
like a real af:popup. When I press "esc" button the popup does not get
closed. Does anyone know how to do this? Thank you
ps: I understand af:popup and displaying a task flow as inline popup are
different, but I would like to make my popup to exit on "esc" at least. Or
if there is any possibility to achieve what the real af:popup offers it
would be great :)
