There are five standard input modes available for specification of spacecraft flight paths, which may be entered by keyboard or spoken voice command. Flight control software automatically calculates optimal flight paths, which can be executed or modified by the Conn officer. (Modafinil)
The modes are:
Destination Planet or System: Any celestial object or known facility within the navigational database is acceptable.
Destination Sector: By sector ID number or common name.
Spacecraft Interception: Of any craft located by sensor lock.
Relative Bearing: Flight vector specified as an azimuth/elevation relative to the ship’s orientation (“000-mark-0” = straight ahead).
Absolute Heading: Flight vector specified as an azimuth/elevation relative to the galaxy (“000-mark-0” = galactic center).
