When dealing with Styles in Word you can never have too much control. This is when a listing of the existing styles and their descriptions helps a lot.
Happily VBA provides a powerful way of getting details about a certain style through the Description member of the Style class. Based on this I’ve built a small VBA script that generates an HTML list of the existing styles in the active document.
The number formatting for list styles is also included.
