KEYR8 (Emacs Friendly Keyboard): Prototype Fabricated


They took a newbie like me through the process of designing the thing and it was fun. Then they fabricated the thing and it rocks.

Emacs friends: there is enough key-space (128 keys) to easily place

  • Control
  • Meta
  • Super
  • Hyper
  • Ultra (Control-Meta-Super-Hyper)
  • Alt
  • Gui


Strong thumb proponents: I’m trying to make it happen here by placing everything on the bottom two rows (including space, Fn, and enter).


Prettifying Org-Mode Code Blocks for Presentations

Org-Mode code blocks are verbose and lovable for literate programming. Rasmus wants to use the raw literate document for a presentation though, so that verbosity won’t do. He explains here how to prettify code blocks. The value-add here is that he doesn’t have to weave (export) the document for it to look great in the presentation; it already does directly in the Emacs buffer.

(Screencast) The Best Emacs Modifier Key Setup for OS X

Here is an easy way to use both Emacs and OS X modifier keys when you are inside Emacs:

Toggle the right-option and function key to switch between using them inside Emacs and using them for OS X.

Addendum: <2016-06-08 Wed 08:22>

I used Karabiner to make ENTER send LEFT CONTROL when chorded. I used OS X to make CAPS LOCK be CONTROL. I didn’t change OPTION and COMMAND. I made this change because Emacs couldn’t ignore the key-event when it was coming from Karabiner.

Here is the code:

 (setq mac-control-modifier 'control)
 (setq mac-right-control-modifier 'left)
 (setq mac-command-modifier 'meta)
 (setq mac-right-command-modifier 'left)
 (setq mac-option-modifier 'super)
 (setq mac-right-option-modifier 'left)
 (setq mac-function-modifier 'hyper)
 (defun help/toggle-mac-right-option-modifier ()
   "Toggle between passing option modifier either to Emacs or OS X."
   (let ((old-ropt mac-right-option-modifier))
     (setq mac-right-option-modifier
           (if (eq mac-right-option-modifier 'left)
     (message "Toggled `mac-right-option-modifier' from %s to %s."
 (defun help/toggle-mac-function-modifier ()
   "Toggle between passing function modifier either to Emacs or OS X."
   (let ((old-func mac-function-modifier))
     (setq mac-function-modifier
           (if (eq mac-function-modifier 'hyper)
     (message "Toggled `mac-function-modifier' from %s to %s."

If You Like LISP Then You’ll Love APL

Notes on Transcription of a talk given by Professor Perlis at the APL’78 Conference held at Foothill College, Los Altos, CA. on 1978-03-29 revealed these gems:

  • Contains all of the best attributes of written language
  • Contains all of the best attributes of LISP… just more so
  • Is a lyrical language
