Microsoft Word’s spell-check is quite good. However, it occasionally puts that squiggly red line under something that is spelled correctly. Maybe it’s a product, place, or company name. Maybe it’s a person’s first or last name. Regardless, most of us just right-click and select “Add to Dictionary” if we know we’ll be using that word again.
But, have you ever wondered where all those words go once you’ve added them to your custom dictionary in Word? And more importantly, have you ever wondered if you could update your custom dictionary in Word? If so, this tutorial is for you because it shows how to access and edit your custom dictionary in Word.
This tutorial is available as a YouTube video showing all the steps in real time.
