Agree. One way to do this would be BeforeSelectionChange having a commandType indicating select forward and select by word.

Yes please:) Cursor and selection are the same thing.

I agree, except that I don't know why we want paste to fire two 'intention' events (paste and input). Seems like we should make it clear that the intention is insert text (type, voice, whatever), remove text (delete, including what text to remove), or paste (so you can clean it up).
