I am unsure if this goes here so I apologize if it doesn't. I currently have a 13.3 macbook air and have classrooms in college that have the tiny desks that pretty much only allow for the laptop and nothing else. My problem is that I can't find a hard cover or something to place over the keys so I can place my notebook over it and write down notes I don't want to type, that prevents me from damaging the keys or pressing them down. Can anyone help with this? I also wanted to know if anyone else knows how to prevent the audio recorder from picking up every little keystroke, regardless of how quiet i try to type, especially when I have to increase input volume to be able to hear the professor.
