Pressing a number key calls up a specific screen directly. The lower right corner
of the screen displays the screen number. Whenever the manual discusses a
screen, it identifies the screen by number (e.g., Screen 1, Orbit Information).
The number keys are used to enter alphanumeric data such as latitude, antenna
height, site name. Depending on the particular screen, number keys may have
other functions; for example, the [8] key for ‘yes'.
