Snapping with dynamic guides
For accurate object alignment and resizing, you can use dynamic guides instead
of setting ruler guides manually or performing selection, transform, and
alignment operations. These magenta-coloured guides are shown between the
vertices of the last three selected placed page objects and the manipulated
object and "visually suggest" possible snapping options such as snap to the
placed object's left, right, centre, top, right, bottom, or to the page centre. You
can include objects to snap to by dragging over objects.
