[TYPO3-seminars] HTML Files?

[Steffen Ziegler]

Hi Oliver,
Thanks for the help,
I've looked in the manual, but I think, unfortunately, nowhere the  
available variables of plugin.tx_seminars.templateFile?

I would like to edit this html here.
Resources / Private / Templates / BackEnd / RegistrationsList.html

Sorry for the many questions :-) So slowly I understand it but :-)

Greetings Steffen
