The order corresponds to the position in the bit string and the KVC code, i.e.
0 for the leftmost bit, etc. The joystick button therefore is in the KVC bit pattern
on the leftmost and has the KVC code 0.
5.2 Joystick
The KeTop is equipped with a 2-axis joystick inclusive joystick button. This is
evaluated by the software and can be read via the KVC server.
To avoid that the joystick is damaged when the device falls to ground, a short
joystick is used.

Value range: -128 to +127 per axis (256 increments)

All information is represented by symbols, there is no text. The display contents
are generated by the control and only shown on the display. The only excep-
tions are the error messages that are displayed directly on the KeTop.
The display has a size of 128 x 128 pixels and provides 13 spaces for the
symbols:

bols used in the KVC server cannot be changed during operation of the KeTop
