Menu selection

Menu items are selected with the cursor, the currently selected item is shown as a raised button and can be selected with either the left or middle mouse button.

Certain commands have trailing optional menus which are made available for selection by using the middle button. The left button will confirm the command `as is' taking defaults for the optional commands. If having descended to an optional menu the user can still select the default command option by entering 'return' to confirm the command.

Note: All commands specified by graphical input device are converted to their alphanumeric equivalent. If alphanumeric information is required selection of such an item will activate the keyboard input, this should be followed by '=' to return to menu input of optional items.

The menu cursor is initially positioned at the last selected item from that menu.
