**Detailed description of issue**  
Hello everyone, I am trying to disable the comment button on the toolbar but unable to do that. As per my understanding it will look something like instance.UI.disableElements([‘’]); but unable to decide the element name. Please guide. Thanks.

**Does your issue happen with every document, or just one?**  
Every document

**Code snippet**

```javascript
instance.UI.disableElements(['fullscreenButton']);
instance.UI.disableFeatures([instance.UI.Feature.Print]);
instance.UI.disableElements(['ribbons']);
instance.UI.disableElements(['panToolButton']);
instance.UI.disableElements(['toolsHeader']);
instance.UI.disableElements(["language", "languageButton"]);
instance.UI.disableElements(["selectTool", "selectToolButton"]);

```

Hello abhirup,

Try:  
instance.UI.disableElement(‘toggleNotesButton’)

Thanks a lot Tyler. It worked. Also can you please guide how to know the toolbar button names exactly so that I can easily modify the toolbar when needed.

Best regards,  
Abhirup
