Focus an inline Datepicker?

Focus an inline Datepicker?

I would like to use the out-of-the-box keyboard shortcuts that are available to the jQuery UI Datepicker widget, but they only seem to become available on the pop-up version once you click inside of a input that is attached, or showOn with a button.

I have to use an inline Datepicker attached to a div.  Is there a way to focus it and use the built-in keyboard shortcuts?  This is for a keyboard accessibility requirement.
