Can someone tell me how I can grab a lisp expression from a stack trace, as in copy it in emacs so I can re-paste and potentially edit it in the repl?

When I move the cursor to the line, the entire text displays in the echo area at the bottom of the emacs window, but when use use CNT-E to move to the end of the line, the line has been truncated and i see "..". I'd like to copy/paste the un-truncated line.

I'm attaching images of what I see.

Kind regards

Jim
