Get record ID in _headerModuleList.tpl (CE)

I'm trying to customize the very top navigation menu and figured out everything except for how to get the module name and record ID inside _headerModuleList.tpl (template which generates the top navigation bar)

What I tried:

- Calling $_REQUEST inside .tpl file, but since the URL contains a # it seems like the module name, record etc. are generated by JS

- Calling $bean->id, $focus->id etc.

- Setting up a custom view then defining module/record id as a smarty variable > defining a custom header in metadata for that view > reading that smarty variable inside the custom header. Problem is that it seems like we can only specify a custom 'headerTpl', but not a custom 'headerModuleList.tpl'

- Tried all relevant smarty loops inside "_headerModuleList.tpl"

May be a powerhouse like Francesca Shiekh , drifterjack drifterjack, Ara Gon would be kind enough to share their experience with this

There's surprisingly very little documentation on this except for standard modifications via admin interface
