pSince the version 1.4, Ted4 and Fred4 can work at the same time with multiple pages and articles in different typographies.
The Regions toolbar allows you to select typography and region on the Articles main tab. See Select typography and region for details.
For pages, as typographies are assigned to titles, on the Pages main tab in Fred4, a typography is automatic selected by by selecting a title.
Relationship of typographies and titles
When you create a title, you have to assign a typography to it. Every title is assigned to one typography. Many titles can be assigned to the same typography. That assignment cannot be changed later, unless deleting and re-creating the title.
Relationship of typographies and regions
There's no direct relationship of typographies and regions, but they're related indirectly through titles. Every region belongs to one title only, but a title can be related to many regions. Therefore, through a title, a typography is related to all the regions that are assigned to that title.
