Enables or disables snapping of schematic elements to the grid. When the button is down, all elements will automatically be snapped to the grid when they are added, moved or resized. Block instances will be moved so that the upper left corner of the block will coincide with a corner of a square in the grid. Connection segments will be moved to the nearest grid line. No elements are moved when this command is invoked; grid snapping only has effect when operating on an element.
