If you are a new Voiceover user or you just forget how to do what you need Siri may come to the Rescue. I had someone tell me tell Siri to close the mail app it would give you Voiceover instructions if Voiceover were running. It did. I then turned off voice over and again said close the mail app it gave instructions as if you were a sighted user. Note you must be specific and say the mail app the messages app Safari app ETC.
