How best to display whether a user is in a global setting vs. a local setting

I am designing an application where the user has a data grid of records and different types of notification: new mail, new tasks, new issues, new assignments. The user can click on the data grid and the user is taken to a record specific page. The navigation and notifications become contextual for that record. I'm fighting with providing some kind of obvious feedback that the user is in a new space-the local record space vs. the global space.

Any ideas on how I can provide this feedback other than just showing a colored box around the local record?

Thanks
