(Emacs) Text is read only?

Question

So I was working in emacs and the suddenly, the slime-repl sbcl says text is read only. Well that\'s great because now I can\'t type anything into it. How do I fix?

Answer 1

Possible cause of such a message may be this: you are trying to print something over the REPL prompt, for example CL-US|ER> (+ 1 2). This text in the SLIME buffer is read-only. Note the space after >, it is the part of the prompt.
