Got it.

Okay. First, let's try '(?\+)

 (define-key gnus-summary-mode-map '(?\+)
   (lambda ()
     (interactive)
     (gnus-configure-windows 'edit-article 'force)))

Still get:

Debugger entered--Lisp error: (wrong-type-argument arrayp (43))

Now let's try: 

 (define-key gnus-summary-mode-map [(control c) (e)]
   (lambda ()
     (interactive)
     (gnus-configure-windows 'edit-article 'force)))

This worked. I now replaced [(control c) (e)] by [(w)] so that I just
can 'w' and have it expanded. Thanks, Steven.

What's the difference between ?\+ and [(w)]. I suppose the second is an
array of lists? But what about the '?' in the first? What does it do?
