2.4 Keyboard
The keyboard consists of the following areas:
Alphanumeric Keyboard
With this keyboard, numerical values and texts can be entered (edited)
in particular fields of the dialogs. For details of editing, see Section 2.6.
In addition, the ENTER key has special significance. Generally, it acti-
vates a marked function:
- In the Situation Display, the data of the marked target or marked
own ship are displayed.
- In the menu, the marked dialog is called up.
- In the dialog, the marked field is opened for editing.
- In the case of editing, the changes made in this field by editing are
put into intermediate storage and this editing field is closed.
The 0 key too has another function over and above the editing function:
it can be used to set the illumination of the display without opening the
respective dialog- see Section 2.7.
Arrow Keys
With these, a selection can be made:
- In the Situation Display, a target or own ship is marked with the aid
of the four keys.
- In the menu, these keys are used to mark the dialog to be opened.
In the dialogs, they are used to mark the field that is to be edited.
During this process, the ArrowUp/ArrowDown keys make the
marker jump to the previous or next field that can be marked, and
(in most dialogs) the ArrowRight/ArrowLeft keys make the marker
jump to the bottom or top field that can be marked.
- In particular editing fields, the ArrowUp/ArrowDown keys can be
used to change the value or to select one of the possible entries.
☞ In these cases, the message Use arrow keys appears in the
dialog.
- In the other editing fields, the ArrowRight/ArrowLeft keys can be
used to change the position of the editing cursor.
The Softkeys
The four keys situated below the display possess functions which
depend on the operating situation. The function involved is shown
inverted in the bottom line of the display. These functions are explained
in the individual sections of these Operating Instructions.
The MENU Key
With this key, the menu is switched on and off. If there is a dialog open,
this key aborts it. In the case of editing, the MENU key has no effect.
