some 20+ years ago I ran into the same issue and my solution was to 
write the code where:

1. Load records onto array(s)
2. Use show command in loop processing to display rows
3. Use waitkey to capture key stroke

@sk will hold the value and by using this method, I was able to create 
custom browse processes where, at times, one row include the equivalent 
of 3 rows worth of data.

Additionally, I was able to give user options to move right/left, 
up/down, top/bottom and gave me countless options to control data 
content and flow.

To do this, you will need a good understanding of use of arrays ... and 
once you write the code, you may never use standard browse processing.
