This will work, but it can create future problems if a different document based on Normal used different settings - and then you re-opened this one. Your instructions cause the TOC styles to be modified for the default template (Normal.dotx). Worse, subsequent levels based on TOC 3 will change as well.Ģ. For some obscure reason, the default is “on” - but with it turned on, any direct formatting change made by a user to an instance of that style will automatically change the style definition! So, if a user decided to make a given TOC 3 line italic, all TOC 3 lines will suddenly become italic. In the Modify Style dialog, be sure to turn off the “Automatically update” checkbox. However, there are two additional points I’d make:ġ. Your method is identical to modifying the TOC x styles with the Modify Style dialog - although I grant that accessing it through the ToC dialog may seem more intuitive.
