The CKEditor 5 preview can be activated manually by adding the @coremedia-blueprint/studio-client.main.ckeditor5-plugin package to the studio app. Execute $ pnpm add --filter "@coremedia-blueprint/studio-client.main.base-app" @coremedia-blueprint/studio-client.main.ckeditor5-plugin@1.0.0-SNAPSHOT from the studio-client root on the command line to enable the package in the Blueprint. If you changed the project version of the Blueprint from "1.0.0-SNAPSHOT" to a different value, please adjust the command accordingly.

Doing so will replace all of the "default" editors in CoreMedia Studio with the CKEditor 5 preview. In this case "default" refers to all editors with no specific editorType set. This includes all editors in document forms, also those added in customer's Blueprint Extensions.

The "default" CKEditor 5 editor and its configuration is set inside the @coremedia-blueprint/studio-client.main.ckeditor5 package, located in the Blueprint. If you want to customize the CKEditor 5 build, you can change the configuration of the editor in this package or even add or remove plugins. This is described in the next section.
