  1. This is the ADM-3A manufactured by Lear Siegler. It had the four arrow keys placed on the HJKL keys.

    vi uses the hjkl keys as arrow keys after the layout of the ADM-3A had hjkl as the arrow keys.

    hjkl keys also double up as cursor keys
    Esc being closer by was used to change between modes. The same is used in vi.

    The keys h,j,k,l double up at arrow keys both in this keyboard and in vi. And in a ton of other things :)

    Using the ADM-3A terminal the Konami Code would be KKJJHLHLBA.
    Bill Joy created vi with what he had available.
    Aren’t you glad Unix wasn’t created using Dvorak?

    ADM-3A. Bill Joy created VI on it. ADM-3A has no arrow keys, HJKL are used for arrow keys. Hence, vim uses HJKL as arrow keys.

    ADM-3A
    The short-hand notation of using the tilde character for the “Home” directory in the C shell, bash and other command shells on Unix and Unix-derived systems derives from the ADM-3A’s having the tilde symbol and the word “Home” on the same key

    ADM-3A terminal

    The vi editor was written by Bill Joy for use on an ADM-3A terminal, which places arrow symbols on H,J,K,L letters

    The use of the HJKL keys as ‘arrow’ keys for cursor positioning.


  12. the use of the HJKL keys for moving the cursor in the vi editor and its descendants

    The ADM 3A keyboard used the hjkl keys as the arrow keys. Vi’s creator reused the same keys.

    The HJKL keys for moving the cursor in VI came about because on this keyboard, the left,up,down,right keys corresponded to the HJKL keys on the ADM-3A keyboard.

    Does this have to do with using h, j, k and l as navigation keys in vi?

    / Remember, you can’t spell “E-V-I-L” without “vi”.
    // Emacs :)

    vi’s Ctrl-H, Ctrl-J, Ctrl-K, Ctrl-L cursor-movement commands derive from this keyboard (ADM-3A)
