Good afternoon. I'm programming an Excel function using Visual Basic. My
function works, but I want to add it the yellow squares telling what kind of
arguments should I introduce in a particular position.

For example, if you use (in spanish language) the function BUSCARV, as soon
you open the parenthesis apperars a yellow square that shows:

BUSCARV(valor_buscado, matriz_buscar_en, indicador_columnas, [ordenado])

It's like a help to know the arguments to introduce. I want that my function
shows this kind of yellow square to help user know what kind of information
should he use.

Thank you,

Nicolás
