Select copy and paste
Highlight and copy selected text instead of whole message
Tap a bubble, tap COPY, move the selectors and tap COPY again.

I have tried the simple paste, but I am trying to paste a screenshot from my clipboard, am I see the screenshot and I see the other things on my clipboard, I can paste other things but I cannot paste the screenshot. When I press long hold in the new message I get the word clipboard and I see my clipboard, but I cannot paste the screenshot and I can't get rid of the word clipboard.
