Documentation for Wayfinder &contexts feature?

I’ve looked over the official docs here: http://rtfm.modx.com/display/ADDON/Wayfinder

There is mention of a new parameter "&contexts", however there is no explanation for what it does.

&contexts (added in 2.2.0-rc1)

If anyone has that knowledge they might add it to the official docs.

Thanks,

In short, if you want to create a menu from a context other than default, use &contexts=`myOtherContext`

Hope this helps.

Thanks for the example. But what if I want to use a template across contexts and need the &contexts param in Wayfinder to also be dynamic? I tried creating a context called "context_name" and then using that in my Wayfinder call, but it doesn’t return anything when I do that.
