"Copy" Response Button.

Hello! I am wanting to implement a "Copy" button that displays on every single response from the agent which users can click in order to copy the agent's response. I have been running in circles to look at the best way to implement this and just need a bit of guidance: can I achieve this out of the box through VF, or should I be looking to implement some custom UI and make use of VF's API? If I need to get down and create something custom then I am happy to, but would definitely prefer to save the effort if I can achieve it through simpler means.
