How to highlight current argument in SLIME

Question

I am using sbcl with GNU Emacs 24.3.1 and the 2012-04-14 release of SLIME, on Arch Linux to write some Common Lisp code. When writing an expression, if I type, for example

(if 

the minibuffer will display

(if TEST THEN &OPTIONAL ELSE)

Is there a mode or SLIME setting that can make the argument that I'm currently editing be highlighted in the minibuffer? For example, if I type

(if (> x y) 

it would be great if

(if TEST *THEN* &OPTIONAL ELSE)

or something similar was displayed in the minibuffer.

The strange thing is that you have documentation in minibuffer with this configuration. Maybe your distribution also loads it from a different location.

Please try this config:

(setq inferior-lisp-program "/usr/bin/sbcl")
(add-to-list 'load-path "~/.emacs.d/slime-2012-04-14/")
(require 'slime)
(require 'slime-autoloads)
(slime-setup '(slime-autodoc))

It tells Emacs to load and use slime-autodoc module that displays documentation and in minibuffer and highlights it as you'd like it to be.

Maybe you'd also like to update to a more recent SLIME version (the current one in ELPA is 20130402).
