### 8.18 Scratch Buffer ¶

The SLIME scratch buffer, in contrib package `slime-scratch`, imitates Emacs’ usual `*scratch*` buffer. If `slime-scratch-file` is set, it is used to back the scratch buffer, making it persistent. The buffer is like any other Lisp buffer, except for the command bound to `C-j`.

`C-j` ¶
`M-x slime-eval-print-last-expression`

  Evaluate the expression sexp before point and insert print value into the current buffer.

`M-x slime-scratch` ¶

  Create a `*slime-scratch*` buffer. In this buffer you can enter Lisp expressions and evaluate them with `C-j`, like in Emacs’s `*scratch*` buffer.
