# How to put an acronym for the first time without showing the long name using the acro package?

I'm dealing with the acronyms in my thesis using the acro package, however, I don't want to see the full long name of a few acronyms. How can I call for the first time an acronym, without showing its full long name?

A MWE: I want to see only UV instead Ultraviolet (UV)

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{acro}

\DeclareAcronym{N}{
short=N,
long=Number
}
\DeclareAcronym{UV}{
short=UV,
long=Ultraviolet
}
\begin{document}
The first acronym I want to see the long name for the first time \ac{N}.
However, the second one, I don't want to see the long form
when I call it \ac{UV}

\printacronyms
\end{document}


You can mark an acronym as used:

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{acro}

\DeclareAcronym{N}{
short=N,
long=Number
}
\DeclareAcronym{UV}{
short=UV,
long=Ultraviolet
}
\begin{document}
The first acronym I want to see the long name for the first time \ac{N}.
However, the second one, I don't want to see the long form
when I call it \acuse{UV}\ac{UV}

\printacronyms
\end{document}


• Unless mark-as-used=first is supplied as a package option, \acs{UV} should do the same as \acuse{UV}\ac{UV}. – Dai Bowen Jan 31 '18 at 23:39
