In all drawing modes, the mouse pointer will snap to a nearby point. This will ensure an exact point is specified by the mouse. To which kind of point it will snap can be adjusted. The LayoutEditor supports 6 different kinds of snapping. The reduced version only supports snapping to grid and to point. All other snapping kinds will need the full version of the LayoutEditor. Snapping can be activated on an individual basis via the main menu and a toolbar. By default, after starting LayoutEditor, only Snap to Grid is activated. Snapping is not active in non-modifying modes like Zoom Mode.
