Now, that must be an American expression, because in my experience, one is more likely to say "learning the ropes".
It means to be getting used to something (usually a new job or occupation).
"Are you an expert climber?"
"No, I'm still learning the ropes/turf" (= I'm still learning the basics)
["Non, je suis toujours en train d'apprendre à me débrouiller"]
