[racket] Subindex and some Latex code withing Slideshow

I've created this procedure. I think it's working for now. Thank you.
(define subindex
  (λ (B i #:font-base [fuente-Base (current-main-font)] #:size-base
[tam-Base (current-font-size)]
        #:font-index [fuente-index (current-main-font)] #:size-index
[tam-index (current-font-size)])
    (hbl-append
     (text B fuente-Base tam-Base)
     (text i `(subscript . , fuente-index) tam-index)
     )))
