How does one control the movement of hot air balloons?

Hot air balloons rise ito the sky because of the fundamental property of the hot air filled in them; air when heated becomes lighter (less denser) than the surrounding cold air. The balloon does not have controls such as accelerator, steering or brake. It is driven by breeze and so there is no control over the flight path. Ascending is by heating the air with the help of burners suspended beneath it. As a result, the balloon rises to find its equilibrium with the surrounding air. Descending is by releasing the hot air from the balloon. Hot air balloon enthusiasts venture out after studying the weather and making sure there are no strong winds.
