The control that sent the message.
Discussion
By default, the action message is changeFont:. This action method causes the receiver to send its action message up the responder chain.
When a responder replies by providing a font to convert in a convert(_:) message, the receiver converts the font by removing the trait specified by sender. This trait is determined by sending a tag message to sender and interpreting it as a font trait mask for a convert(_:toNotHaveTrait:) message.
