To enable the F-keys you have to modify the text file /home/xnc/bin/lancia in Xterminal by xmeditor, it isn't quite easy in that (some kind of linux) system and it could make problems to start the software, if you make mistake.
It was necessary to write extra parameter -SiTasti on line with parameter -TempoVis 200.
For example it could be like: via quote "-TempoVis 200 -SiTasti $normswitch",
where the original line was: via quote "-TempoVis 200 $normswitch"
There were different versions, so the line could be sligtly different with various parameters.
