The navigate script provides a convenient graphical user interface to the DVO shell and database. To use it, simply load it into the DVO shell with the input command. It is useful to always load this script by including the input command in your ~/.dvorc file. Once you have loaded the script, you can start it by typing navigate. You can navigate around the sky, then exit the script at any time by typing 'q'. This allows you to issue DVO commands related to your current position. You can then resume navigating by restarting the script.
