There are three keys on my computer whose paint is starting to show severe wear: E, N, and O.
E is pretty obvious; it’s the most common letter in the English language. But I find it interesting that the next most common letters – T and A – look as good as the day I bought the machine.
I have a strong suspicion that N gets a lot of extra use on my computer because it’s the shortcut for the pencil tool in Illustrator. I hit that a LOT, from a slightly weird angle as I’m usually controlling AI with my right hand on the stylus and my left hand on the keyboard.
O, I’m not sure of – in Illustrator it’s the shortcut for the mirror tool, which is not one I’m constantly using. Maybe I just hit command-O to open files a lot?
