Language
The viewer defaults to your browser’s language setting, falling back to English. To change the language, click the Language button in the toolbar or select a language from this Settings dialog. Supported languages: English, Chinese (Simplified), and German.
Tip
When the language is set to Automatic, a Language button appears in the toolbar. Choosing a specific language hides this button and moves the setting here to the Settings dialog, freeing up toolbar space.
