How can you see the inbox while composing a message in Full Screen Mode on Mac?

The ability to see the inbox while composing a message in Full Screen Mode on a Mac can be achieved by clicking anywhere in the viewer, outside of the message. This action effectively allows you to exit the focused view of the message you are composing and return to the inbox, providing a convenient way to interact with other emails without having to close the compose window.

While other options may seem plausible, they do not facilitate viewing the inbox in Full Screen Mode. Clicking the Show/Hide button or using menu options might be useful for other purposes but not specifically for toggling the inbox view in this context. Therefore, the option that allows you to navigate back to the inbox by clicking outside of the message frame is the most effective method for achieving that goal in a streamlined way.
