Open OIDS from the Finder by double-clicking the OIDS application icon. When the list of galaxies appears, select one and click on the "Play" button. You can also double-click on the galaxy name to play it if you prefer.
There are seven actions that you can perform with the V-Wing fighter. The default keyboard controls are shown below. (Your keyboard may differ from the one shown below.)
Note: This configuration can be changed with the "Keys" dialog, found on the "Special" menu at the top of your screen. Most Macintosh keyboards have a limited number of keys that can be activated at any one time. The "qualifier" keys, such as the shift, control, option, and command keys are immune to this problem and can all be activated at the same time. Unfortunately, system extensions such as Easy Access can interfere with the use of these keys. If you want to use these keys, then disable Easy Access while playing OIDS.
