On our version of Gosling's emacs we use
a modified electric-lisp-mode along with some other functions that Jed
wrote. Here are the main things that I like:

paren-pause	Gets bound to ')'. It flashes corresponding '(' either by
                temporarily moving the cursor up to the '(' and pausing, then
                returning, or if the matching '(' is off the current window
                then show the matching line in the mini-buffer.
                It also fixes the indentation of the ')' if it is on a line
                by itself to match the column of the corresponding '('.
                Complains if there is no match.

nl-indent 	Gets bound to linefeed. Inserts new line and properly indents
                the next line. A simple "proper indent" is that if there is an
                open unmatched '(' then the next line should be indented 4 from
                the unmatched '('.

re-indent-line  Unbound function to repair indentation of current line.

indent-lisp-function
		Unbound function to fix up the indentation of entire lisp
                function from (dX to ).

electric-lisp-semi
                This function is bound to ';'. It takes you to the nth column
                when pressed so you can start a comment. We unbind this one.
                I like to deal personally with every ';' (or '%').

forward-sexpr	Bound to ESC ')'.
backward-sexpr  Bound to ESC '('.

Its nice to have an abbrev table for lisp.

lisp-comment-mode
 		Bound to ESC 'c'. Asks for a function name. After carriage
                return it does this:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;
; <function-name>
;
; <leaves-cursor-here>
;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Now as you type its in "text mode", when it gets near the end of the line it
automatically starts a new line, inserts ';' and a space. Any time you press
newline it does the same. When you enter carriage-return the cursor is moved
to the line below the box and you're back in lisp-mode. 

You can move your cursor back into a previously built box and enter
^U, ESC 'c'. This will kill-to-end of line and put you back into the
"text-mode" described above.

There are some others, but these are the useful ones. If you would like
the mlisp files for these functions, let me know.    Harold.
