dow is removed from the screen. In addition, the Maximize keyboard
(Keyboard_Maximize) is activated if available.

Here, you can set a different bitmap pattern for the key; at present, only the entry
$ExtBmp1 is possible for keys highlighted in color, for example, the [RETURN] or
[TAB] key. If this entry is not used, then the entry including comma must be
omitted.

Here, you define the size and positioning of the key. For parameters left blank (,,,) or
parameters that are not available, the default value is always set.
The default value for the size is defined through the StdKeySize entry in the

X-position after the previously defined key in accordance with its size.
