This mode supports selection of multiple objects. It recognizes the difference between a left and a right click. Left click is used for selecting desirable, or positive points. Conversely, right click is used for marking undesirable, or negative points.

The Auto mode aims to streamline object selection. It allows users to click on an object one or more times to select multiple regions. If you wish to deselect or remove any regions, hold down the Shift key and click on the regions you want to remove.
