geostats cluster map drilldown: what token/s are available?

[cmeo]

I am using the cluster map visualisation and geostats, and I'd like to be able to drilldown on each cluster and show formatted details of all the entities in that area. I can get the raw events for the sourcetype with the default drilldown, but what tokens are available if I want to drill to another dashboard instead? The docs seem to be vague on this point, and the applicable Answers are more than two years old.
There seems to be a thing called a geobin which is added to the events in the initial map, but I can see how to generate a useful filter for the target dashboard and panel.

OK thanks to the responders, problem solved. Create tokens for the four values passed (N, S, E, W limits) and make sure the target search includes lats and longs.
For instance:

sourcetype=customer| eval l_location=upper(location)|eval state="VIC"
| lookup locations suburb as l_location state output lat lon
| where (lon >= $lon1$ AND lon < $lon2$) AND (lat >= $lat2$ AND lat < $lat1$)
| sort surname1

| table firstname1 surname1 phone1 email1 address location

And the thing that threw me: I'm in the southern hemisphere, note that the relation operators for lats are reversed because all our lats are negative! Thanks to my good lady wife for spotting that one...D'oh!

@cmeo Predefined tokens for Map can be found at the following Splunk Documentation link.

The docs are fine as far as they go, but the Auto drilldown for the map looks like this:
sourcetype=customer | eval l_location=upper(location) | eval state="VIC" | lookup locations suburb as l_location state output lat lon | search lat>=-35.85938 lat<-35.15625 lon>=143.43750 lon<144.84375

So it is automatically generating a latitude and longitude range presumably corresponding to the radius of the cluster marker, and supplying this in the search parameters. I cannot see how to pass this range in custom tokens, since the properties of the cluster marker aren't available. The statistics table for the parent map has four fields: geobin, latitude, longitude and a count (of what I'm not sure, not customers certainly) if there's a way to group the lats and longs I don't see it.
As an experiment I tried passing $click.lat.value$ into the child dashboard to see what I got, which was exactly one lat value--no range. So, what magic is going on here?

You are probably looking for $click.bounds.orientation$. In your example above,

| search lat>=-35.85938 lat<-35.15625 lon>=143.43750 lon<144.84375

the search with tokens would have been

| search lat>=$click.bounds.south$ lat<$click.bounds.north$ lon>=$click.bounds.west$ lon<$click.bounds.east$

(maybe I've confused east and west there, you might have to check). But this is how you get all events matching the lat/lon bounds produced by the cluster.
