Well after lusting after one for 34 years (I remember 1984's ad), I finally got one today. It is a 13" last years model (I have too many USB devices to go to USB-C) with the 256gb flash drive. I have already had a problem with it, where random keys on the right side of the keyboard would not work. Option pressed five times seems to have fixed the issue. It is just enough different from my Linux laptop to be confusing. So what are some of the important tips and tricks I need to learn to use this thing to its full potential?
