I can’t find them on my keyboard… 
It reminds me a little anecdote.
I was working in a cybercafé a long time ago. One day, a client, clearly puzzled after struggling with his computer, came to me and asked, “Where’s the ‘n’ key on your keyboards? There’s no key ‘n’?” I pointed to the “n” key on his keyboard and said, “The ‘n’ is here.” He thanked me and returned to his writing.
