Emacs 24.4, Pretty Lambda λ But No Pretty Form Feed ^L
Emacs 24.4 included the Pretty Lambda λ mode. But it didn't include the more practical pretty form feed ^L mode. [see Emacs: Show Form Feed (^L) as Line]. Send a bug report to gnu. Alt+x
you probably already knew all this, but Emacs: How to Define Keys is the most useful tip for emacs.

A correction to yesterday's post.
auto-revert-mode is local to current file. To turn on globally, use
Emacs: Cycle Fonts by Command (minor update)
emacs “company-mode”, a name completion framework. I heard many good things about it. Haven't used it myself. You might try it. It's at: http://company-mode.github.io/
emacs auto-revert-mode, due to magit-mode
auto-revert-mode in past month. Pretty good. It automatically update buffer when file on disk changed (by some other program or editor)
not sure why it's on. I looked at my init files but it's not there. Must be some packages that turned it on, but not sure what. Maybe magit-mode did it, since i recall upgrading it. A web search confirmed it. (https://groups.google.com/forum/#!topic/magit/shCpTvyyygI) Magit did this sometimes in Feb.
i'll let it sit for a while.
i did notice that some buffers don't auto revert, but after reading the magit change discussion, it seems magit turned it on only for files under git.
so, for better global experience, better turn it on globally.
Emacs: Let's Kill Texinfo
ESR, the ever trouble maker, wrote a blog about his successful push for GNU emacs dev to use git. [Dragging Emacs forward By ESR. At http://esr.ibiblio.org/?p=5211 , accessed on 2014-03-03 ]
he also mentioned, the possibility to kill Texinfo.
it should've been dead since 2007.
in general, GNU and the Open Source have like a 5 to 10 years lag in adopting technology, for reasons that are inadvertently intentional and or simply incapable.
Emacs: Sync Environment Variable from Shell
thanks to samhalicke's comment at Emacs: Set Environment Variables within Emacs#comment-1268323059
This emacs package will sync your shell's environment variables on Mac OS X when you started emacs from GUI. https://github.com/purcell/exec-path-from-shell (it doesn't seem to work for Microsoft Windows, as i see no code dealing with registry. [see Microsoft Windows Registry Tutorial])
much keyboard updates.
xfq mentioned that by default, emacs will tally abbrev expansion. See his comment at Emacs: Abbrev Mode Tutorial#comment-1266520734.
i didn't know that. The abbrev tutorial i gave basically thwarted that. Thanks to xfq.
