Thank you, a simple \setupalign[hanging] inside the caption is sufficient. 
I encountered some difficulties when I tried to insert it automatically via
\setupcaptions[style={\setupalign[hanging]}]
I got an error message, probably due to expansion.
Finally, I found

\newtoks\HANGTOKS
\HANGTOKS={\setupalign[hanging]}
\setupcaptions[headstyle=\tfx\it,style=\the\HANGTOKS\tfx]

This works fine now. Some other problems resulted from a long forgotton 
\setupbodyfont[11pt] following the first setup command. Now I have 
\setupbodyfont[11pt,ams,modern] - I noticed this because switching font 
size turned off haning, which is fixed by the new order in \setupbodyfont.

Ooops, sorry... But still, I have this example file:

\setupcaptions[headstyle=\tfxx\it,style=\tfxx]
\starttext
    \placefigure{The same bla bla \digits 1000 times and
       then again: $x\times y$.}
       {\framed{How nice!}}
     And shouldn't the next formula be {\tfxx at least $10^x$ times}
     smaller? Well, it isn't!
\stoptext

Math mode does not adapt to the current font size. This is not limited to 
captions, so is this a known problem? For the \digits, the code you sent to 
Marco (Re: Questions/Comments) helps by avoiding math mode.

Thank you,

Eckhart
