Locking menu bar at the top of the screen

All,

I was wondering if there is a way to lock the menu bar at the top of the screen in a similar way that the Ticket Action bar is locked when you scroll down. I think this would be particularly useful when there are particularly long tickets. Please let me know if there is a way to do this programmatically or with an extension.

Thanks!
