Snap to Guides 

      The Snap to Guides option of MacSoft Publisher causes the 
 object tool or the sides of an object being moved to align themselves 
 to the page guides. 
    Snap to guides is activated or made inactive by selecting Snap to 
 Guides from the Page menu. If this option is currently in force, 
 selecting Snap to Guides deactivates it. If the option is not in force 
 selecting Snap to Guides activates it. A  check mark is displayed 
 next to this item in the Page menu when it is in force.
