# Rich Text Editor Settings

In this chapter we will learn how to change settings for the Rich Text Editor.
We will add a button to the toolbar to underline the selected text.

In the `config.js` file we will create a new button.

```jsx
import React from 'react';
import createInlineStyleButton from 'draft-js-buttons/lib/utils/createInlineStyleButton';
import Icon from '@plone/volto/components/theme/Icon/Icon';
import underlineSVG from '@plone/volto/icons/underline.svg';

const UnderlineButton = createInlineStyleButton({
  style: 'UNDERLINE',
  children: <Icon name={underlineSVG} size="24px" />,
});
```

Next we will add the button to the toolbar.

```jsx
export const settings = {
  ...defaultSettings,
  richTextEditorInlineToolbarButtons: [
    UnderlineButton,
    ...defaultSettings.richTextEditorInlineToolbarButtons,
  ],
};
```

## Exercise

Add a button to the toolbar to style a text selection as `CODE`.
