XF 1.3 Forum subtab/submenu/subnav: show/hide content

Hiya Guys,

Just a simple questions, one the image bellow:
  1. What is the name of the bar where is "Mark Forums Read, Search Forum, etc"?
  2. On this bar, how can I show or hide links from/to a specific group or user, let's say "Mark Read"?
  3. On this same bar, how can I include links in this "subtab/submenu"?
I've to say that I loose a bunch of hair trying to find this template.

Thanks a lot!
