Editing Tools

The Editing Tools are a selection of tools that can be used to manipulate various aspects of your session, ranging from moving objects around, selecting ranges, zooming, drawing automation, stretching or shrinking regions in time, and finally just auditioning audio in a region.  Selecting a tool will change how your mouse interacts with objects on the editor canvas to match the properties of that tool.
