I wrote this a while back in PHP.  I was very simple. The first thing I 
did was to render data grid on a
browse like format.  From the resulting query I created an array with 
unique IDs for each row.  This array
of course was kept in a session variable.  When the user expanded the 
record (full view mode), by virtue
of associating the unique ID to the row and the row number within the 
array, I know the Next and Prev record IDs.

So, with this information I placed links which will trigger a query 
(AJAX) to retrieve the adequate  record
based on chosen option.

I remember I included links to choose alpha A - Z so that query will 
retrieve records based on chosen
letter  -   Say for instance, if you were browsing through your vendor 
list and you were looking for
vendors that started with C, you will simply click on the  < C > link 
and up came your query.

Funny thing is that I wrote this for the same reasons you stated here 
... Given that I have used filePro for
such a long time, I wrote this PHP application to emulate much of the 
filePro features I have grown used
to.

Good luck!
