Hello. Unfortunately, not possible. If you try simulating "F" key press with URL rule it gives off this error message.

Failed to execute 'requestFullscreen' on 'Element': API can only be initiated by a user gesture.

Fullscreen can only be initiated by the user for safety reasons. Otherwise, a malicious script could discretely initiate fullscreen and pretend to be a trusted website (bank, etc) and hijack user information.

You can learn more about this type of phishing attack from this article.
