word/letter frequency, key chord design

2 very interesting articles related to word/letter frequency, in particular, for the purposes of creating abbrevs, or key chords.

ELisp: Earth Coordinate to Google Map Link (minor update)

emacs org babel: elisp and clojure always session, ruby session require inf-ruby, python is good properly support session and no-session

Emacs: Delete Current File πŸš€ (minor update)

Emacs Lisp Examples (minor update)

Emacs Select Word Command Problem (Major update. Removed relying on the painful emacs syntax table. Back to simple text based search.)

Emacs Org Mode Bable bug. For emacs lisp, session is always on

* test session; no session

#+BEGIN_SRC emacs-lisp :exports both
(setq x 3)

: 3

#+BEGIN_SRC emacs-lisp :exports both
(+ 2 x)

: 5

save the above as session-test.org, then open it, M-x org-mode. Move cursor to the elisp code block, press C-c C-c to eval. Repeat for the second block.

The expected result for second block should be error of unknown variable x.

These are keys starting with β–€ Menu n from Emacs: Xah Fly Keys. This key set is for commands that are β€œharmless” β€” even if called accidentally. They usually do prompt or do some display changes, and never edit anything.

the Esrille keyboard can be ordered now outside Japan. See its home page: http://www.esrille.com/keyboard/. My review at: Esrille New Keyboard (M-Type and TRON) from Japan
