Formatting Marks - Hard on the Eyes?

"Those things are so hard on the eyes." This comment came in from a new user of LeaderGuide Pro, which turns Word's formatting marks on automatically. You can turn them off using the Paragraph Mark toggle switch on Word's Home ribbon.

You can also use this keyboard shortcut to turn these marks off:  Ctrl+Shift+8

In case you are wondering what formatting marks are, here is a link to a good article about them:  http://wordfaqs.ssbarnhill.com/NonprintChars.htm

The last paragraph explains why LeaderGuide Pro turns them on for you. They help you.

Many Instructional Designers and course developers I talk to wouldn't work in Word without the formatting marks turn on. What about you?
