One can capture the cursor location in the browse using @br - row in browse
window.  If you close the window, set something like br(2,.0)=@br.  You then
can use that information to calculate your pushkey.  Just keep in mind that
this is the row in the browse window starting at the top and not the line #
of the cursor position in the window.
