Trying to use map facility in Scheduler

I can’t work out how to do this.
It might help if I could find the documentation.
The link ( … dars/10363
doesn’t work.
I suspect this extension will work well when I can sort it out, but I’m struggling, since I’m needing to use guesswork.
I also can’t seem to access any way of adding any more than an event title in the back end, because when I edit an event (doubleclick in Events Administration) it only allows me to edit the title itself.
It could VERY WELL BE that I’m missing something very simple.


PS. I’m using Joomla 2.5
