Edit Typed Content Once Its in a Library?

Double-click on the type asset in your CC Libraries panel and it will open in a new InDesign window. Make your changes, and then close that file. This automatically updates the type and you’ll see the change in the asset thumbnail. If you want to make a separate instance of the type so that you have two versions, Right-click on the type asset and select Duplicate, before you make any changes to the original type asset. Then edit the duplicate version.
