Thank you Wolfgang, but I was wondering about the standard \startnarrower.
Many (some) commands allow setup assignments, the use of which overides but does not change the default. This is a very useful feature of ConTeXt that suggest could be generalized. \startnarrower is but one example.
Changing the command is simple but I would drop the second
argument when you want to change the left/right etc. values
because you can say “left=4cm” etc. to get the desired margins.
startnarrower has a weird interface. Ideally, it should just support keywords:
\startnarrower
   [
     leftmargin=...,
     rightmargin=...,
     alternative=(left|right|both),
     spacebefore=....,
     spaceafter=....,
     indenting=....,
     indentnext=....,
     before=....,
     after=....,
   ]
That’s more or less what I use for the “narrow” alternative in the annotation module.

I would prefer such a parameter driven narrower environment myself (do we even need
the left, middle and right option when we can set absolute margins) but keeping the current
interface for backwards compatibility make things a little bit ugly.
