<P>Tk allows 'tab-key' ordering by the order in which you pack your widgets. One way to change this behaviour is to bind a key event to the focus method of the 'next' widget in line.</P>
<P>In this snippet, I bound the return key to the next 'Entry' widget in line. Uncomment the line noted in the code if you want to wrap around.</P>

<CODE>use Tk;

my $bar = $otherwin->Entry->pack;
