evaluate expression in scratch buffer

evaluate expression in scratch buffer

[William Payne]

Hello, I want to evaluate the following expression:
(insert (prin1-to-string (w32-select-font)))

I read that I should evaluate it in the scratch buffer, so I typed it in
there...but what do I do to get the actual evaluation to occur?

Thanks for any replies

C-h a eval RET

[Of these, the functions I find more useful are:]

(snip)
eval-buffer		      M-x eval-buffer RET
  Command: Execute the current buffer as Lisp code.
(snip)
eval-last-sexp		      C-x C-e
  Command: Evaluate sexp before point; print value in minibuffer.
(snip)
eval-region		      M-x eval-region RET
  Command: Execute the region as Lisp code.
(snip)

In lisp-interaction-mode (which is what the *scratch* buffer uses), C-j 
is mapped to eval-print-last-sexp.  Just position the point after the 
last closing parenthesis and press C-j.

Go to the closing parent and hit "C-j".

You can find out what special commands any buffer provides with `C-h m' and

`C-h b'.
