That works too with a long press at any time
oops. @UKHeliBob yes you are right the original code does the same.
So it was a "peace of cake" for chatGPT to leave the code as it is.
In the meantime I compiled the code in the arduino IDE version1.8.19
it spits out this error
C:\Arduino-Pure-Portable\arduino-1.8.19\portable\sketchbook\libraries\MD_Parola\src\MD_Parola.cpp:41:21: error: void value not ignored as it ought to be
MD_Parola.cpp:41:21: error: void value not ignored as it ought to be
never encountered such an error before.
Seems to be in the library. So what is wrong here?
the function with the error
bool MD_Parola::begin(uint8_t numZones)
{
bool b = _D.begin(); // method return status
// Check boundaries for the number of zones
if (numZones == 0) numZones = 1;
#if STATIC_ZONES

#endif
_numZones = numZones;
#if !STATIC_ZONES
// Create the zone objects array for dynamic zones
_Z = new MD_PZone[_numZones];
b = b && (_Z != nullptr);
#endif
if (b)
{
for (uint8_t i = 0; (i < _numZones) && b; i++)
{
b = b && _Z[i].begin(&_D);
}
if (b)

Using library MD_Parola at version 3.7.3 in folder: C:\Arduino-Pure-Portable\arduino-1.8.19\portable\sketchbook\libraries\MD_Parola
exit status 1
Error compiling for board Arduino Uno.
As far as I have started to research on that error. This error occures if you define a function void but want to return a value. In this cas the function is defined bool
bool MD_Parola::begin(uint8_t numZones)
{
bool b = _D.begin(); // method return status
I do not yet understand what the compiler does not like
As opposed to the 'war of cake'? Must have been a sweet truce!
Or was it like a treaty that only lasted while dessert was served?
LOL ! 
I was looking for the peace-logo in the smileys but did not find not even a "piece" of it
here you go ( (it's an emoji)
