Editing in Pages, Word, and other word processing apps for college

iOS and iPadOS

Hey Applevis users,
I'm having issues trying to figure out how to edit with apps such as Pages, Word, Notes, Evernote etc. on my iPhone and IPad using VoiceOver. I'm wanting to swiftly move around a document and edit what I need too and get back to writing as soon as possible. I have Voice Dream Writer and I'm lost on how to use it. I would love some help with learning how to edit a word processing document with a word processor using VoiceOver.

A side note for all of you kindle and iBooks users. HOw do I select a particular line(s) of text and highlight them?

Thanks for any advice anybody can give me.
