Copy or CTRL+A only response

In some cases I want to use the response for further testing. For this I need to copy the response.
For this I'd like to copy the whole response, or at least be able to click in the response field and only select the response when pressing CTRL+A. Currently, it also selects the Request attributes, title, buttons, etc.

Note: While this is similar to downloading the response, it's a little different, as it doesn't require to download a file for further uses.
