So I just got my HHKB in and I'm trying to set the Fn key to the left side, but I must be doing something wrong. I got the Delete --> Backspace to work fine by turning on switch 3, but when I turn on switch 4, left diamond + ;'[/ does not equal arrow keys. Am I mistaken in that left diamond + ;'[/ with switch 4 on is supposed to be arrow keys or is this keyboard simply defective. (blank keyboard....left diamond is the key directly to the left of the spacebar right?)
