Most of the numeric keys have also been assigned special characters,
arithmetic characters or the plus sign. The special characters are iden-
tified in white, in the top left corner of the keys concerned.
To enter the plus sign, the special character or the arithmetic character
you require, press the F
N
control key (see Figure 2-3) and, in addition,
the appropriate numeric key.
If you release the F
N
key, you can return to entering the characters of
the basic numeric key assignment.
The cursor keys are used for navigation (e.g. for scrolling) or to move
the cursor. The following figure indicates the equivalents of the Panel
PC cursor keys on conventional PC keyboards:

The keyboard layout for Windows 98 has been set to ”English/USA
International”. When using an external keyboard with the ”English/
USA International” layout, the key codes of the internal and external
keyboards are identical; for example, if you enter a ”y” on the external
keyboard and a ”y” on the internal keyboard, you get a ”y” on the dis-
play in either case.
2.1.3 Integrated mouse
The integrated USB mouse with the two mouse buttons is a ”piezo
mouse”, i.e. the direction of the mouse pointer movement is determined
by the pressure position on the center circular button and the speed of
the mouse pointer movement by the intensity of the pressure. The
parameters can be modified under ”System Setting/Mouse”.
If you wish, you can also connect an external mouse via the front USB
(refer to Section 2.3).
