[racket] a few small Scribble questions

None of the things that you want are directly available, I think. For
many of them, you can use `make-element-id-transformer' to set the way
that an identifier is typeset by `racketblock', etc. (in which cae
you'll probably want to use the various `racket...font' functions).

Here's an example:

 #lang scribble/manual
 @(require (for-syntax racket)
           scribble/racket)

 @; `tree' as a syntactic form:
 @(define-syntax tree
    (make-element-id-transformer
     (lambda (stx)
      #'@racketkeywordfont{tree})))

 @; `leaf' as a variable:
 @(define-syntax leaf
    (make-element-id-transformer
     (lambda (stx)
      #'@racketvarfont{leaf})))

 @racketblock[
  (+ x (tree leaf leaf leaf))
 ]
