Questions on how to format notes or email on an iOS device running iOS 9 .1

Hi all,
I hoping someone can help me with this. I am trying to format notes or email messages on my iPhone 5s running iOS 9 .1. By formatting I mean, bolding underlining and italicizing text, or changing the font of a selected text. Is this possible? If so how can I do this with voiceover? Thanks for any advice.
