[support] views - menus - arguments

Hello All, I seem to be missing something w.r.t.connecting views with arguments to menu items passing through the same arguments. In other words: how can i define a menu item pointing to a view of the form "content-type/%"? I have looked at Context and Menu_token modules, but i still have the feeling i'm missing a common way to handle this. Any help greatly appreciated! Best, Toon
