Keys PgUp and
PgDn are used for turning pages within the text.
Keys INS and
DEL serve for inserting and deleting characters.
The above listed units (monitor and keyboard) constitute the permanent part of NC and are
transported together with the control in any case of configuration.
The NC keyboard is fitted with repeater-type keys. This means
) that a depressed key produces an immediate effect,
) that a held-down key produces an effect again after a programmed delay (Typematic Delay),
) that, with the key held down permanently, the appropriate code will be entered into the
CPU of the system over and over again at a programmed rate (Typematic Rate).
The delay (TD) and the rate (TR) can be set with the help of parameter 1121 TYPEMATIC
(for details see Parameters).
1.1.2 Information Displayed in General Displaying Area and the Status Bar

– in the bottom line are the fields of current captions of softkeys,
– above - in the middle of screen - is the general displaying area,
– while the top three lines form the status bar.
