Darstellung und Hauptszene

Die Hauptszene verbindet Kern, Karte, Figur, Anzeige und Dateien:
fester Takt, Laufen, Stein schlagen in Reichweite, Speichern mit F5,
Laden mit F9, Pause mit Esc, automatisches Speichern alle zwei Minuten
und beim Schließen. Die Karte erscheint in Platzhalterfarben, bis in
M1d ein Stil gewählt ist. Ein Werkzeug macht Bildschirmfotos ohne
Handarbeit.
