If, for the browse line record that you allow the user to view (a popup,
perhaps?)
and its associated functionality, you do not need to take down the browse
before re-execution, then you should be able to use a combination of
SHOW=PKEEP for the browse along with a conditional PUSHKEY "[CDWN]"
just before the browse line is executed.

If you do take the browse down before re-execution (to provide some
multi-layer
functionality), then I think you do need to use pushkey to do the whole job
 - and it is doable - you can build a separate lookup routine (using the
same
index that you use in the browse lookup) with factors: parent key,
# lines showing in the browse, rec# of last viewed record (capture this
before showing a detail record) to generate the proper string to push
(i.e., "[DTAB][DTAB][CDWN][CDWN][CDWN]").
