Social Sourcing Merge Fields of TBE?

Content

Hello,
We intend to implement Social Sourcing function of TBE, and need to custom "Modern + Selected Jobs (email)"of Campaign Template.
(Navigation:Sourcing Center > Configuration > Messaging > Campaign Templates)
Though I reviewed the social sourcing Configuration Guide, there are no information about it.
(Such as "##Job.special.full_url##".  What does it display?)
 
If you have any information about it please tell us how to custom it.

Many thanks,
Yurie
