Hi,
I am often surprised that some nice-to-have feature is already
present in ConTeXt and I just wasn't aware. But I am not sure about
this one.
Is there something like an adaptive structure code which keeps track
of the nesting level? In this example the first structure would
become the chapter, the second one a section, etc.
\starttext
   \startstructure [title=Alpha]
     \startstructure [title=Beta]
       \startstructure [title=Gamma]
       \stopstructure
     \stopstructure
   \stopstructure
\stoptext
This would ease moving around sections, which might end up as
subsections and vice versa.
There has always been this trick:

\definehead[level-1][chapter]
\definehead[level-2][section]
\definehead[level-3][subsection]

\startnamedsection[level-1][title=Alpha]
     \startnamedsection[level-2][title=Beta]
         \startnamedsection[level-3][title=Gamma]
             1-2-3
         \stopnamedsection
     \stopnamedsection
\stopnamedsection

or

\definehead[levelone][chapter]
\definehead[leveltwo][section]
\definehead[levelthree][subsection]

\startlevelone[title=Alpha]
     \startleveltwo[level-2][title=Beta]
         \startlevelthree[level-3][title=Gamma]

but there's also

\startstructurelevel [title=first lower level]
     \startstructurelevel [title=second lower level]
         \startstructurelevel [title=third lower level]
             test
         \stopstructurelevel
     \stopstructurelevel
\stopstructurelevel

and here's 'level-002.tex' from the test suite:

\definehead[xxxxxxsection][subsubsection]
\setuphead [xxxxxxsection][color=red]

\definestructurelevels[main][chapter,section,subsection,subsubsection]
\definestructurelevels[next][chapter,section,subsection,xxxxxxsection]

\starttext

\startstructurelevel [main] [title=first top level]

     \startstructurelevel [main] [title=first lower level]
         \startstructurelevel [main] [title=second lower level]
             \startstructurelevel [main] [title=third lower level]
                 test
             \stopstructurelevel
         \stopstructurelevel
     \stopstructurelevel

     \startstructurelevel [main] [title=first lower level]
         \startstructurelevel [main] [title=second lower level]
             \startstructurelevel [next] [title=third lower level]
                 test
             \stopstructurelevel
         \stopstructurelevel
     \stopstructurelevel

\stopstructurelevel

\stoptext
