Hi,
there was a question on the Stackexchange site [*] with a problem
for the \starthanging environment when the alignment is R2L.
Here is shortened version of the example:
%%%% begin example
\useMPlibrary[dum]
\starttext
\starthanging[location=left]{\externalfigure[dummy][width=4cm,height=3\lineheight]}
\input tufte
\stophanging
\blank
\startalignment[righttoleft]
\starthanging[location=left]{\externalfigure[dummy][width=4cm,height=3\lineheight]}
\input tufte
\stophanging
\stopalignment
\stoptext
%%%% end example
The problem is that \hangindent behaves the same for L2R and R2L
alignment unlike
the other formatting commands (\hangindent or \leftskip) for paragraphs.
%%%% begin example
\showframe[text][text]
\setuphead
[subject]
[align=lefttoright,
indentnext=yes]
\starttext
\startbuffer
\subject{Normal paragraph}
\input ward
\subject{Leftskip}
\start
\leftskip 4em
\input ward\par
\stop
\subject{Parindent}
\start
\parindent 4em
\input ward\par
\stop
\subject{Hangindent}
\start
\hangindent 4em
\hangafter -2
\input ward\par
\stop
\stopbuffer
\title{Left to right}
\startalignment[lefttoright]
\getbuffer
\stopalignment
\title{Right to left}
\startalignment[righttoleft]
\getbuffer
\stopalignment
\stoptext
%%%% end example
