Question on implementing buttonMarkup

[ajacinto]

Thanks for this awesome plugin. I just had a question about the documentation for buttonMarkup.

I've been trying to get the numeric style like how it's rendered in the demo, so I was trying to set the buttonMarkup settings, but I can't understand how the value of {{SUP:attr}} is acquired and how I should define this in options.

If this is my footnote:
<sup id="fnref:1"><a href="#fn:1" rel="footnote">1</a></sup>

What value should I use for buttonMarkup below?

var bigfoot = $.bigfoot(
{
deleteOnUnhover: true,
preventPageScroll: false,
hoverDelay: 250,
activateOnHover: true,
buttonMarkup: ?
}
);

Thanks! The PayPal donation link also wasn't working btw. I owe you a coffee. :)
