I mean, in retrospect, probably stupid questions, but things like, "What's this Caps Lock key for?" or "What's this Num Lock key for?" You know, that thing? "You know, do people really use it?
Retrospectivamente, es probable que fueran preguntas tontas, del estilo: "¿Para qué sirve la tecla Bloq Mayús?" o "¿Para qué sirve la tecla Bloq Num?".
