Double Bucky

(C) 1978 by Guy L. Steele, Jr.

(Sung to the tune of "Rubber Duckie")

    Double bucky, you're the one!
    You make my keyboard lots of fun
      Double bucky, an additional bit or two:
    (Vo-vo-de-o!)
    Control and Meta side by side,
    Augmented ASCII, nine bits wide!
      Double bucky, a half a thousand glyphs,
               plus a few!
        Oh,
        I sure wish that I
        Had a couple of
            bits more!
        Perhaps a
        Set of pedals to
        Make the number of
            Bits four:
        Double double bucky!
    Double bucky, left and right
    OR'd together, outta sight!
        Double bucky, I'd like a whole word of
        Double bucky, I'm happy I heard of
        Double bucky, I'd like a whole
            word of you!

Control as a modifier key (not a bucky bit) certainly predates that, if the dates in the link are correct.

The most important thing that distinguished the Lisp Machine keyboard was that it had dedicated parenthesis keys. According to my sources, that was so you could hold a Hefty bag of nitrous oxide in one hand, and type s-expressions with the other. (Gumby can you verify this? ;) )

You might be able to put "symbolics" keys on your keyboard: https://deskthority.net/photos-f62/round-6-the-cappening-t15... Don't make the mistake I did and focus too hard on the tool and not enough on the work :)

I used "Keyboard Maestro" for this. I tried out some other tools, but they mostly didn't work or were too bothersome to configure. It's definitely worth the cost, as it made a Mac usable to me, although my keymap is quite different from yours, which is kind of a point with this kind of software :)

I was using Linux and StumpWM (a Common Lisp/Emacs-based WM, and Enlightenment before that) for a couple of years, so I thought that full support for personal keymaps is a given in any serious computing environment. I was pretty shocked to learn that on Mac OS you can do very little keybinding, if exchanging a few keys positions can be even called that. Fortunately, it looks like I'm going back to Linux soon.

As a tmux/vim user those extra control keys look amazing, there are too many layers fighting over too many control keys in my current setup, I'd love to have something like a dedicated vim accelerator, a dedicated tmux one, a dedicated console one and a dedicated desktop manager one.

Is anyone selling keyboards like this? What happened to those really expensive customizable keyboards from a few years back?

In command contexts "." refers to the current line (e.g., :.,$s/a/b/ will perform the a -> b substitution from the current line to the last line of the file). That comes from ex which likely copied that from ed. I've seen "." used similarly in other contexts. 8-bit Microsoft BASIC used "." for the current line -- "LIST ." would list the last line that had been listed or edited. A number of assemblers use "." for the current assembly address.

The point being that there is a bit of a tradition of using "." for "the current thing" so there's a sort of sense in using it for the most recent command.

If you're really curious get in touch with Bill Joy.

I've seen some work like this with 4coder. Having extensions written with native code that is dynamically linked makes this sort of thing make more sense if you want to minimize lag.

4coder is still very alpha at this point is easy to break but the low level primitives exposed leave it open for easy experimentation with little cruft to peal away first. It also very C++ focused so YMMV.

Emacs? It has a gajillion modes.

I smell an Emacs user!

On an ASR33 Teletype, backspace simply moved the carriage one character position to the left.

Rubout was a different concept entirely. The ASR33 had a paper tape punch and reader. The Rubout character was 0x7F, i.e., it had all bits set. So, to "rub out" an erroneous character from the paper tape, you could back the tape up in the punch to the desired character (by pressing a button on the punch; there was no character that invoked this function) and hit Rubout; this would punch the tape at all seven holes, changing whatever character had been there to a Rubout. (The software ignored Rubout characters on input.)

When the world moved on from Teletypes, it was natural for people to want a single keystroke that meant "delete the previous input character". But there was evidently some divergence of opinion in the industry as to whether that should be Backspace or Rubout -- notwithstanding that the ASR33's concept of Rubout didn't really map at all onto the new hardware.

Since that keyboard does not seem to have a “Delete” key, I assume that “Rubout” performs that function.

This is probably a holdover from typewriters. Backspace moves the cursor. Rubout erases.
