Location Key

First of all, thanks so much for making an accessible calendar plugin! There aren’t many options out there that are accessible, so I am very grateful for your contribution.

I like the Category Key feature that can be added above or below the calendar with the [my_calendar] shortcode. I am also needing to add a similar feature, but for Locations.

Would instructions for adding this feature be included in the user guide? or is it available in the Pro version?
