I don't know the answer to Pedro's original post, but that particular
keybinding is already available, <menu-key>-\. 

If you wanted to map a different key to something, you could run this
code to find out what the key looks like and then use that in your

(define kcanvas%
  (class canvas%
    (define/override (on-char e)
      (unless (eq? 'release (send e get-key-code))
        (printf "~s\n" (send e get-key-code))))

(define f (new frame% [label ""] [width 200] [height 200]))
(define c (new kcanvas% [parent f]))
(send c focus)
(send f show #t)
