Mouse Wheel Click

When the Selection & Panning checkbox is selected, the priority is given to selecting map objects. Clicking the mouse wheel in the map window activates the Selection by arbitrary area mode. Once the contour is drawn, objects within it are selected. Map panning is performed by holding the Ctrl key, pressing the mouse wheel, and moving the mouse. To exit the object selection mode, disable the mode (in the main application toolbar).

When the Panning Only checkbox is selected, clicking and dragging the mouse wheel performs map panning. This mode is recommended when the left mouse button is used for placing contour points (e.g., when creating objects using the Vector Map Editor). In this case, panning with the left mouse button is disabled.
