# changeFont(_:)

This action method changes the font of the selection for a rich text object, or of all text for a plain text object.

```
func changeFont(_ sender: Any?)
```

## Discussion

If the receiver doesn’t use the Font panel, this method does nothing.

This method changes the font by sending a [`convert(_:)`](/documentation/AppKit/NSFontManager/convert(_:)) message to the shared NSFontManager and applying each NSFont returned to the appropriate text. See the [`NSFontManager`](/documentation/AppKit/NSFontManager) class specification for more information on font conversion.
