The navigation menu changes based on which engines are installed upon your
ship.  Starting on the far right side of the menu, if you have maneuvering
thrusters installed, then the THRUSTERS button will appear.  In the middle, if
you have a fusion drive installed upon this ship, the FUSION DRIVE and the
NAVIGATE TO buttons will appear.  If you have a hyper drive installed upon the
ship, the HYPER DRIVE button will appear on the far left.  Below that, if you
also have maneuvering thrusters, then the PLOT COURSE button will be visible.
However, if your ship is in orbit around a planet (meaning your ship is drawn
directly over a planet) the hyper drive and plot course buttons are replaced by
the LAND button.

If your ship's velocity is greater than the speed of light, meaning you are at
hyperspeed one or greater, then your fusion drive and maneuvering thrusters are
useless.  The PLOT COURSE button is also replaced with a FULL STOP button which
causes the ship to drop out of hyperspace at its current coordinates.

THRUSTERS BUTTON
This button brings up an eight-direction pad which allows you to pick the
direction you wish to maneuver this ship in.  In addition, the center button
allows you to rotate this ship to a specific heading.

FUSION DRIVE BUTTON
This button is used to move a ship to a position that is visible on screen.
When selected, the navigation menu disappears and a grid appears over the play
field.  Select the new square you want your ship to move to, and that coarse
will be set in.  The technology level of your fusion drive will determine how
many turns it will take to reach the new location.

NAVIGATE TO BUTTON
In the event that the coordinates you want to move this ship to are not on
screen, select the NAVIGATE TO button.  A numeric pad will appear on the screen
and you can enter the new coordinates, anywhere in the universe, that you want
this ship to navigate to.  The ship will then proceed to those coordinates
using its fusion drive.  The technology level of your fusion drive will
determine how many turns it will take to reach the new location.

PLOT COURSE BUTTON
This button is similar to the NAVIGATE TO button in the respect that it also
prompts you for coordinates.  However, these coordinates are fed into your
navigation computers and after the next turn processing, your computer will
spit back out a new heading and distance to reach those coordinates using your
hyperdrive.  Once a new heading is calculated, this ship is automatically
turned to that new heading.

HYPER DRIVE BUTTON
This button allows you to activate this ship's hyper drive.  If you used the
PLOT COURSE button on the prior turn, the hyper drive will echo back that it is
programmed with a heading and distance and all it needs is a speed.  A numeric
key-pad will open up, and you can enter the hyper speed you wish to use to
travel the pre-calculated distance.  Upon reaching the end of the journey, the
navigation computers will automatically stop the ship.  If you select the HYPER
DRIVE button without plotting a course, the ship will accelerate forward on its
current heading, but will not stop unless you hit the FULL STOP button.  If you
select the HYPER DRIVE button while on route to a new destination, you can
accelerate or slow down the ships progress along the route.

FULL STOP BUTTON
When selected, the ship will drop out of hyperspace and if a pre-determined
course was already calculated, it will be lost.

LAND BUTTON
This button appears when this ship is over a planet.  There are two types of
settlements you can land upon.  The first place you can land is your home
planet.  On the home planet, you can take and leave minerals, remove additional
missiles, mining equipment, and planetary shields, and also access your home
world's factories, ship building capabilities, and also repair damaged
components of this ship.  The other type of settlement you can land on is all
other astral bodies in the universe including asteroids, stars, and other
planets.

Whenever something can be taken from or left on a planet, there will be a + and
a - button.  To increase the number of something, such as workers or mining
equipment, press the + button.  To remove something, such as minerals, press
the - button.  In both instances, a numeric keypad will appear and you can load
or unload whatever amount you wish.
