AutoCAD 2015 question

Hi, ok so in AutoCAD 2015, my DWG file has multiple drawings in it, how do I alternate between the drawings in the DWG file? In 2013 it will have a little tab on the bottom, but in 2015 it is gone and I cannot swap between the drawings. 

The one file contains multiple drawings, but I cant swap between the drawings.
