Should emacs be different? Alternate Title: New vs. Old: the interface issue that just won't go away
controversy. See: 〔《Should emacs be different? Alternate Title: New vs. Old: the interface issue that just won't go away》 At http://www.reddit.com/r/emacs/comments/2yp9v7/should_emacs_be_ifferent/ 〕
my opinion posted there.
decades old issue. Note:
* there are just as many, who used emacs for 2 decades, believe that emacs default keys are the worst. You can see some of it in ergoemacs comments, some of which i've collected.
* you don't hear these people much because, such opinion are not inline with the emacs community, are raely propagated.
* i think emacs should turn on cua mode by default. More urgent than ever. Tons of new editors are still cropping up every year, and seems more so in recent years. Atom, Facebook's Atom derivative, and even Microsoft Code.
* In the past 5 years, in emacs 23 and 24, some controversial UI issues have been fought hard, and decision made towards modernization. For example, visual line arrow key movement. transient-mark-mode.
* emacs default keys are scientifically Repetitive Strain Injury inducing.
* emacs default keys, are not just bad for newbies, but are scientifically, technically, inefficient for expert emacs users.
* The ~7 de facto standard keys for copy cut paste undo open new save... if emacs adopts them, then, the keys would be technically, scientifically, more efficient, for long time emacs users, not just for newbies.
* I personally believe, emacs should adopt the ~7 de facto standard keys. because: 1, it will increase emacs users by i estimate at least 2 fold within one year. 2, it will make emacs keys more efficient for long time emacs users.
i have over a hundred articles on keybinding issues. The point mentioned above, especially about keys, i have scientific data to backup. If anyone is interested, ask me. It's all on my site, by the way.
I love emacs. Emacs the system, i think is still unbeatable in many ways. But its keys, i think is scientifically one of the worst, and as well the number one problem for new users to swallow. There are lots packages that provides alternative, but vast majority of emacs users (i believe more than 60%), are not those we see in online blogs or forums, and don't even know how to use packages. It needs to be the default.
for what's worth, that's my opinion. Thanks.

List of Emacs Starter Kits (minor update)
emacs 24.1 variable: switch-to-visible-buffer
switch-to-visible-buffer → If non-nil, allow switching to an already visible buffer.
This variable was introduced, or its default value was changed, in version 24.1 of Emacs.

Normal PC Keyboard with Many Thumb Keys
if you want a normal PC keyboard but with lots thumb keys for emacs hyper super, get this one.
for more, with mechanical keys, see: Should You Type Space After Comma? and Tiny Space Bar on Japanese Keyboards
Once you get such a keyboard, you can remap the thumb keys. For how to, see Keyboard Tutorial: Layout, Keybinding, Key Macro ⌨
this would beat many keyboard hacks that makes space bar do multiple things or quick key combos like df as leader key.
Emacs: Open File in External App (minor update code)
Emacs: New Empty Buffer (minor update)
Emacs: Xah CSS Mode, is ready for public use.
Major feature is keyword completion, and coloring of all keyword, not by form. (so, if there's a typo (invalid CSS), you'll know because it won't be colored.) See the link above for screenshot and more features.
Please give it a shot. I'm looking for comment and suggestions. I'll be submitting to MELPA. Thanks.

Xah Emacs Packages
in past weeks, i polished several of my packages and submitted them to MELPA. Check them out in above link. In emacs, just call
list-packages, then search for “xah”. [see Emacs: How to Install Packages Using ELPA, MELPA]
I also like to thank Steve Purcell, who is currently maintaining MELPA. It's huge amount of work. I noticed, everyday, he actually tests incoming packages to check on quality. That's several per day, like full-time job.
Steve Purcell also wrote many emacs packages. You can follow him at:
