**Text Boundaries Template for Word 2013/2016/365**
Word 2013/365 changed the text rendering engine in Word so that "text boundaries" are around individual paragraphs rather than displaying the page margins. Many people prefer the old method.
This is a zip file containing two letter-size
macro- and text-free templates and a read-me document. Documents created using one template will display text boundaries like they were displayed in Word 2003-2010, they will be in compatibility mode. Documents created using the second template will
display with a pseudo text boundary that is actually a page border set to be one point from text. Those documents will not be in compatibility mode. This is a work-around, not a solution, but may be helpful. See the Read Me file for directions. Version 15.3
