        %{fin[ish][ frame-number]\tExecute until selected stack frame returns.

          If no frame number is given, we run until the currently selected frame
          returns. The currently selected frame starts out the most-recent frame
          or 0 if no frame positioning (e.g "up", "down" or "frame") has been
          performed.

          If a frame number is given we run until that frame returns.}
