CT target without options

Good day,

I wonder what a rule like this:
-A foo -t raw -j CT

actually does?
It shows up like this:

Chain foo (0 references)

target     prot opt source               destination
CT         all  --  anywhere             anywhere             CT

but what does it mean?
The opposite of --notrack?

thanks for your answers

Hello list :)

I'd still would be happy to get an answer on that old query of mine... Thanks a lot!
