Reply to one part of an agent's answer
You no longer have to reply to a whole answer. Point at the sentence, table row or lines you mean, and the agent gets exactly that.
Reply to a selection
Select text in an agent's reply, or in a file in the Files pane. A small Copy · Reply button appears over it. Click Reply, write your note and press ⌘/Ctrl+Enter to send it.
A quote from a file includes the file path and the line numbers, so the agent can open the file at the right place.
Send several quotes at once
Press Enter instead to add the quote to the message box. Collect quotes from different replies and files, then send them together in one message.
Copy copies the selected text.
