The ViewCube and navigation bar 

The ViewCube is an AutoCAD-only tool and is not available in AutoCAD LT, whereas the navigation bar is available in both AutoCAD and LT, but in LT, it is somewhat limited in features. If you don’t see the ViewCube, simply go to the top left of the display area and click on the – sign and select ViewCube and Navigation Bar:

This — sign won’t show up on AutoCAD LT, but you can use the NAVBAR command to turn it on or off.
