So, what you are seeing is the consolidation of transcripts from the top to the transcript tab for all interactions and the display of the threading of the conversation. If you are allowing them access to the Interaction Details, I would suggest they just download the transcript and copy/paste from that export. The other way would be a simple Client App that could retrieve the transcript and copy it to the clipboard or display it for the agent. you could have that open on the left or as a widget in the interface.
If the agent is still in the chat, the easiest is to use CRTL-A then CRTL-C in the chat window.
