This is an old help article that pre-dates the new Style options.
So to format the normal text in Word, do these simple steps.
1. Select the first instance of Normal text, typically your first response.
2. Right click (or similar on Mac) on the Normal text style in the Toolbar.
Select all instances of the normal text.
3. You can then apply your Normal text style by clicking the Normal Text button again (single left-finger click).
Or you can modify the style and format all of the normal text to your desired font choice.
