+Se puede acceder @qq{lateralmente} a algunos grobs desde dentro de la
+función de callback de otro grob.  Éstos se encuentran relacionados
+normalmente como @qq{layout objects} (objetos de presentación) en la
+sección @qq{Internal properties} (propiedades internas) de un
+interface de grob.  Se usa la función @code{ly:grob-object} para
+acceder a estos grobs.
+
+
+Se presentan más abajo como ejemplo algunas formas de addecer a grobs
+desde dentro de una función de callback de NoteHead, pero la técnica
+no se limita a las cabezas de nota.  Sin embargo, la función de
+callback de NoteHead es especialmente importante, porque es la función
+de callback implícita que utiliza la instrucción @code{\\tweak}.
+
+
+La función de ejemplo que se define abajo (\"display-grobs\") no es
+probablemente tan útil, pero muestra que se está accediendo
+efectivamente a los grobs.
