The Head-Up-Display Whenever you're inside your Stardrifter, your HUD displays a lot of information from your main computer. At the top of the screen are displayed the class and name of your remote target and local target (More on classes later). In the bottom left are displayed your distance from your remote target in light-years, and your distance from your local target, in dyams. You'll also notice that there are messages displayed on the inner rim of your helmet's visor itself. In the very top left corner, the date is displayed (the Felisian timekeeping system is explained later in this document), and along the top right are displayed the shortcut keys for the currently selected menu on the computer window. Along the bottom of your visor rim are displayed the current gravity (in FGs), temperature, air-pressure and your own pulse-rate. Finally, in the bottom right of the HUD's main screen is displayed your computer's status. This can be one of many different messages, most of which should be f airly self-explanatory, so no list is provided here. Your HUD is lit by four small diodes in the corners of the visor rim. To brighten or darken these, use the "+" and "-" keys on your keyboard. Finally, please note that when you are on a planet's surface, your HUD will not normally display any data on its main screen (though the data around the helmet rim will remain in place). When you press a key, it may display a status message in the center of its main screen to let you know what pressing that key did.
