in emacs, there are systematic ways to find out which shortcut is
associated with which command, and which command has what shortcuts.

This is describe-key and describe-function.

For detail, see:

• Tips on Long Term Emacs Productivity
  http://xahlee.org/emacs/effective_emacs.html

In lisp modes, there are several commands to eval lisp code. Each has
a shortcut, and you may also define alias so you can type less.

(defalias 'eb 'eval-buffer)
(defalias 'er 'eval-region)
(defalias 'ee 'eval-expression)
(defalias 'elm 'emacs-lisp-mode)
(defalias 'eis 'elisp-index-search)

The C-j you mentioned is not a shortcut for any of them in any lisp
mode i know of.

Exactly, and by default they're bound to `C-h k' and `C-h f'.

Nope, `C-j' is bound to `eval-print-last-sexp' in all lisp modes (elisp,
common lisp, I guess scheme, too).

No, C-j is newline-and-indent in Lisp modes which are meant for
programming. But in lisp-interaction-mode it does eval-print-last-sexp.

Ups, you're right.  That's a local customization I have in my .emacs.
Shame on me!

C-h k : OK thanks!

lisp evaluation command

[moueza]

hi,
C-j unavailable for me, what is the minibuffer equivalent command for C-j ?

Hi,

the "lisp evaluation command" which always works is:

In lisp modes that's `eval-print-last-sexp'.
