where is the value template_templates used?!

[Dionysis]

in includes/adminfunctions_template.php

in the function print_style

there is the dropdown option list with name=\"styleEdit_$printstyleid\"
and value=\"template_templates\">" . $vbphrase['edit_templates']. which shows all the templates if you click on it.

my question is where the hell is the code that grabs the name/value pair and returns the command to show all the templates?

I'm trying to seperate the templates into 2 or more groups (probably an array) and i want to change the value=template_templates to something w/ a variable and have it only return that group of templates at a time.

any one have experience w/ the template manager? help please?
