I dont get the last shortcut "Zentr." ... It's like "Zentral..." or "Zentrisch..." or "Zentri..." or "Zentrum" it's not clearly defined! Is this from a train or race simulator?
At least I try:
Geschw. (Speed/Pace) - Niedr (low), Mitt (middle), Hoch (high)
Schw. (I think it's "difficulty") - Leicht (easy), Mittel (middle/medium), Schwer (hard)
Kontrolle (control) - Alt (old), Neu (new)
Strecke (track) - Aus (off) An (on)
Zentr.(I think it's "Zentrum") - Links (left) Rechts (right)
