[NTG-context] suppressing hyphenation and setlayerframed

[Eros Albertazzi]

1-
I would like to suppress hypenation in a text of a \startfiguretext 
within a \setlayerframed
I am aware of the thread in jan 03 on the list and the fact 
that\setupalign[nothyphenated] (or \nohyphens) overshoot the right margin
On the other hand I do not know where to put the 
align={left,nothyphenated,width} that was suggested in the reply

here is the piece I work with:

\setlayerframed[page][preset=righttop, 
column=1,line=30][width=\dimexpr((\paperwidth-2cm)/2),align=]{\getbuffer[b]}

with the buffer:

\startfiguretext
[left][]{}
{\externalfigure[t1][width=.2\textwidth]}
... <<<nohypened text>>...
\stopfiguretext


2-
still awfully raw on context I am looking for the options of 
\setlayerframed, list and meaning, command that is absent from manuals 
or web info-tools

in details.pdf some examples are build with 
\setlayer[..][..]{\framed[..]{..}}

what's the difference, if any, betwwen the two form?
