To begin with, you need to give Word permission to enable macros.
You need to adjust some settings in Word before that can happen. Word doesn’t automatically allow macros to work their magic with a fresh install.
If you’re a Mac user, see this tutorial for enabling macros in Word 2011. Some macros can help you to see things in your writing that you wouldn’t otherwise see. *Macros are tiny programs that can make writing and editing tasks more efficient and accurate. If you have a fresh install of Word, you may have trouble adding or running macros*.
