Cheers Vasilis! Usually all you need to do is type 'look' to get the names of all the things you can interact with. There isn't a command that directly highlights names as such. If you get stuck I'll be happy to dispense hints!
I think it was, but for some reason I just did not clue into what it could be used for. I tried one idea and got a unique response so I didn't bother to try others. My mistake!
