Not really. If you look at most apps, they provide either untitle or
empty page, and has user pref to set whether to do that or just have
nothing.

Even so, you don't need *scratch*. You can just have “untitled”.

It is a ballpark estimate. Sad to say, but my experiences tells me
that tech geekers (you being one good example), lack any basic
knowledge of social things that are generally classified under social
science. Maybe u too old to do so, but you might want to take a few
courses under social science heading in college, like history,
psychology, philosophy, letters. Or, u can read some text books n u
can buy them online at amazon.com or browse used books store. Esp the
older editions, are just few dollars.

To answer your question or help you think more specifically, you can
actually try to spend 1 hour thinking about this specific issue. Start
with, for example, how many people in the world actually code elisp.
What's the percentage with respect to programers. What's the
percentage with respect to all IT professionals. (look up definition
or ask a professor in social science department on what is meant by
“IT professional”) Also, think about what emacs is supposed to be, and
think about its relation to writers. Think about how many writers are
there in the world, what's their percentage with respect to, say,
programers.

Perhaps the concept of thinking for one hour on academic subject is
something you've never done. That's ok. I can suggest that instead of
just philosophizing on it, you could instead do a activity approach.
Try to go to library or online and find statistics about these issues.
Alternatively, if u have a lot money, you can pay research firms that
answer these questions for you. Typically, big corps like Microsoft
and Apple spend, i dunno, hundreds of thousands dollars on it yearly.

To you, a emacs tech geeker, doesn't seems a nuisance. To your
grandma, or even most professional, or another tech geeker of the vi
faction, it stops them using emacs.

Please understand, the issue is not:

(1) whether i should write a patch,
(2) nor is it about writing a patch that do something you think is
better.

To illustrate (1), for example, suppose you say that fucking in the
ass is not moral and government should ban it. Then someone says why
don't you stop fucking in the ass yourself.

To illustrate (2), suppose you say that fucking in the ass should be
better done with lubes first. Then someone says why don't you try to
fuck in the ass with butter.

Yes, thanks. Yesterday, i have done more polishing on the article
( http://xahlee.org/emacs/modernization_scratch_buffer.html ) Among
the editing is a addition about the shortcut. Quote:

«Note: the proposed keybinding “Ctrl+n” and “Ctrl+w” need not be part
of this proposal because emacs already use “Ctrl+n” and “Ctrl+w” for
basic cursor movement and cut. However, it could be adapted in
conjunction with newly designed Ergonomic Keybinding. (see below)»

For keybinding issues on this, see the above paragraph.

You are not a typical software user. You are a tech geek.

I suggest you enhance your critical thinking skills. You can start by
reading Wikipedia here:

See above.

Yes. Thank you.

it's not umimportant trifle. Familiarity is important aspect of

you are right. Thanks for correction.

Yes, but what's your point?

Thanks for your feedback.

I do not mean they should be the final form. That's why i said it's
experimental draft implementation. I started with elisp code for
ergonomic keybindings, then my studies lead me to find minor
improvements on text manipulating functions and other things such as
keybindings for common operations such as Open, Close, Save, and among
things is the discovery of emacs problems in creatig new empty buffer,
closing unsaved buffer with potential data lose, etc. Long story
short, it leads to a solution to the *scratch* and i have implemented
that doesn't have much to do with ergonomic keybindings.

You suggested few times about how i should code elisp in some way and
submit the patch. Perhaps, let me suggest to you, that you should try
to take what code i have, polish it, and start a discussion in emacs
dev lisp, and send the patch into GNU emacs.
