How to invoke the Change Tracking capability?

There is documentation here about a Change Tracking capability:

https://docs.rws.com/806356/64908/sdl-tridion-docs-14-sp3/change-tracking

But it does not say how to invoke this change tracking. Is this what is used by the web client capability to generate a report comparing one publication version against another?

I also notice there is an "XML Change Tracker Settings" page in the web client. Same Change Tracking?

Thanks
