Memory Locations have many uses beyond marking points on your session timeline. If you frequently find yourself switching between two or more views, Memory Locations are a great way to customize different track views that you can jump to quickly. When you create a new Memory Location and the dialog window opens, choose "None" for the Time Properties. Check boxes for various track parameters, such as zoom settings, track height, show/hide tracks, pre/post roll, and group enable. That way you can, for example, have one Memory Location set to recall a vocal track in jumbo size, zoomed in close, with the other tracks hidden.
