Hello, on https://tug.org/begin.html you could find a lot of useful links.Further I would recommend the LaTeX Companion, which should answer quite all possible questions.Good luck Alois------ Originalnachricht------Von: HeimeDatum: Mo., 6.

In this code, the third level picks up the colour value from level two.  
But I want the third level to take the default red colour value.

How does one apply a default set of keys at the start of each environment 
exactly ? Shouldn't \keys_set:nn {tlapis_keys} {#1} do that ?

    \documentclass[a4paper,10pt]{article}
    \usepackage{xcolor}
    \usepackage{enumitem}
    
    \ExplSyntaxOn
    
    \makeatletter
    \setlistdepth{13}
    \newlist{wvTlaps}{enumerate}{13}
    \setlist[wvTlaps]
      {
        label=$\langle$\the\enit@depth$\rangle$\arabic*.,
        left=0pt, parsep=0pt, itemindent=8pt,
      }
    \makeatother
    
    \tl_new:N \l_tlapis_kl_tl
    \tl_new:N \l_tlapis_lv_tl
    
    \keys_define:nn { tlapis_keys }
      %% Define Key-Value Interface within namespace tlapis_keys.
      {
        kl .tl_set:N = \l_tlapis_kl_tl,
        kl .default:n = {red},
        kl .initial:n = {red},
    
        lv .tl_set:N = \l_tlapis_lv_tl,
        lv .default:n = {},
        lv .initial:n = {},
      }
    
    \NewDocumentEnvironment {wvTlapis} { O{} }
        {
          \keys_set:nn {tlapis_keys} {#1}
    
          \tl_if_empty:NTF {\l_tlapis_lv_tl}
              {
                \begin{wvTlaps}[format=\color{\l_tlapis_kl_tl}]
              }
            {
              \begin{wvTlaps}
                [format=\color{\l_tlapis_kl_tl},
                 label=$\langle$\l_tlapis_lv_tl$\rangle$\arabic*.]
            }
          }
        { \end{wvTlaps} }
    
    \ExplSyntaxOff
    
    \begin{document}
    
    \begin{wvTlapis}
        \item First level
        \begin{wvTlapis}[kl=green]
            \item Second level
            \begin{wvTlapis}
                \item Third level
            \end{wvTlapis}
        \end{wvTlapis}
    \end{wvTlapis}
    
    \end{document}

I want to see how I can handle package options using expl3, but have not found useful
information about how to do it.  The Latex Team provide help in Tex Stack Exchange, 
an amazingly terrible place to ask for help.
