Where can I adapt details of the newsflash Module?

The design of the newsflash is composed of several  modules: In the Master Design the newsflash is called $newsFlash:ID. The Design Module $newsFlash contains the placeholder $news which calls the Newsflash Intro Templates, which are listed one below the other.

These Design Modules are administrated under Tools & Administration > Design & Layout > Master Design & Design Modules/Design Modules. The newsflashes are administrated under Website & CMS > Menus > Newsflash/Overview.
