Options displayed in the main menu (left part of the screen) include:

OPTIONS	EFFECT
Zoom	After entering this option a ‘pencil arrow’ is displayed on the screen, and the pencil is moved around the screen using the cursor arrows. During this operation LATITUDE & LONGITUDE are displayed at the top of the menu. Click mouse at <EXIT> to finish. A new plot, centred on the new zoom-centre, is now displayed.

Translate	Interactive translation & rotation of continent or adding lines/points /characters to the existing continent. After entering this option a ‘pencil arrow’ is displayed on the screen, and the ‘pencil’ is moved around the screen using the cursor arrows.
Translate	Move pencil arrow to any position on the continent: Type 1 to record position Move pencil arrow to a new LAT-LONG on the globe and, Type 2 to record the new position Click with mouse at <EXIT> to finish A new plot showing the continent translated by an amount that takes point 1 to point 2 will now be displayed
Point	Type P to draw lines between consecutive points Click with mouse at <EXIT> to finish Save continent in the main menu using a different file name
Annotate	Move pencil arrow to any position on the continent Type A to record position Type a single character in the input edit box which will appear, e.g. T for Tillite, E for evaporites etc. Click with mouse at <OK> to register character Click with mouse at <EXIT> to finish Save continent in the main menu using a different file name

Scale	Select scale (magnification) centred around zoom-centre. Click with mouse at the appropriate scale value (50-2000%)
