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:

(help/on-osx
 (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."
   (interactive)
   (let ((old-ropt mac-right-option-modifier))
     (setq mac-right-option-modifier
           (if (eq mac-right-option-modifier 'left)
               'none
             'left))
     (message "Toggled `mac-right-option-modifier' from %s to %s."
              old-ropt
              mac-right-option-modifier)))
 (defun help/toggle-mac-function-modifier ()
   "Toggle between passing function modifier either to Emacs or OS X."
   (interactive)
   (let ((old-func mac-function-modifier))
     (setq mac-function-modifier
           (if (eq mac-function-modifier 'hyper)
               'none
             'hyper))
     (message "Toggled `mac-function-modifier' from %s to %s."
              old-func
              mac-function-modifier))))
