With View › Snap to Grid on, a selection moved with the Selection, Group
Selection or Direct Selection tool lands on the grid: on each axis,
whichever of its two edges and its centre is nearest a gridline (every
subdivision, 9 pt by default) moves onto it. Snap to Grid takes over from
Smart Guides and Snap to Point while it is on, as it does for drawn points.
