Translator configuration
The Translator translates the selected text of your content right in the editor, with Google Translate or Yandex Translate. Its settings are in the Translate section of your Dashboard's Settings tab: the service, its API key, and the languages it starts with. The Translator is a part of the Premium plan.

The Translator's buttons are hidden on the toolbar of new API keys. To show them, click Translate in the copy of the toolbar in the N1ED → Toolbar row and check Show on the toolbar, and do the same for the two buttons next to it (see UI, toolbar and widgets).
When you use the Translator you can change the languages on the fly right from its buttons: one swaps the two languages, the other one opens the languages for the rest of the session. What you set here is where every session starts.
The translation is requested from the browser of the user who edits, so the API key is visible to anyone who can open the editor page. For Google, restrict the key to the Cloud Translation API and to the address of your website in the Google Cloud Console.
