Datepicker ui Altering Button Panel

Datepicker ui Altering Button Panel


In the Datepicker demo with the button panel it says
"Each button is enabled by default when the bar is displayed, but can
be turned off with additional options. Button text is customizable."
But I can't find any place that says how to do that, any ideas? Also
wondering if there is a way to add custom buttons to the panel like
you can do with the dialog. What I'd like to do is change the text for
the today button to "View Current Month" and add "Add New Event"
button with custom actions to the panel.
