That's what you had asked for.  Using '&' after a command, a shell
executes the command in the background.  Lack of '&' causes the
command to be executed in the foreground.  Try these two commands in a
bourne-like shell (such as ash (FreeBSD sh), ksh93, bash2, bash3) ...

 sleep 15 && date &

 sleep 15 && date


In your situation, blackbox runs in the background & bbkeys in
foreground.  If you wanted to run bbkeys only if blackbox runs, then
do AND operation ...

  blackbox && bbkeys


... optionally send the both commands in the background (say, if there
are more commands to be run after the two commands)...

  blackbox && bbkeys &
