# Manually add an entry to the list of tracked entries

I feel like I'm missing something simple, but I can't manage to write a macro to manually add an entrykey to the list of tracked entries in biblatex such that \ifciteseen will be true.

What am I doing wrong?

\documentclass{article}
\usepackage[style=verbose,citetracker=true]{biblatex}
\makeatletter
\def\sbl@blx@trackentry@global#1{%
\ifbool{citetracker}
{\xifinlistcs{#1}{blx@bsee@\the\c@refsection}
{}
{}}
\let\trackentry\sbl@blx@trackentry@global
\def\showtrackedentries{\csshow{blx@bsee@\the\c@refsection}}
\makeatother
\begin{document}
\trackentry{augustine}

\showtrackedentries

\cite{augustine}

\showtrackedentries

\cite{augustine}

\showtrackedentries
\end{document}


biblatex detokenizes entry keys, so the test fails unless the argument to \trackentry is run through \blx@xsanitizeafter. This works:
\def\sbl@blx@trackentry@global#1{%
