XF 2.2 Copying a forum template

[canina]

I want to copy the forums page (the main page) to another tab, in order to make changes there. I understand that I need to make a new template and copy the content name of an existing template.

For the test, I copied the PAGE_CONTAINER and list_forum templates, but in the 2 attempts the parameters did not pass. How do I get their parameters into the template?
Thanks
