C-d deleting region considered harmful

C-d deleting region considered harmful

[Miles Bader]

I notice that various deletion commands will now delete an active
region.  The most obviously useful to newbies is DEL (aka backspace),
as that's what other platforms use, and I don't have any problems with
that (and I might even use it occasionally)

However, the effect of "C-d" deleting the active region has been
driving me nuts for quite a while.  I accidentally end up deleting
something I didn't intend to about 10-15 times a day... usually I
notice and am annoyed but can immediately hit undo, but occasionally I
don't immediately notice, and end up being very very confused until I
reconstruct what happened.

I thought I might get used to it after a while, but so far, despite
the frequency with which it happens, it's every bit as annoying as it
was when it first started happening.

Is there any particular _reason_ for C-d to have this effect?  C-d is
not a binding used by other platforms, so it has no obvious utility as
newb-bait, and it's no more convenient than C-w.  It seems almost
entirely pointless.

I propose removing this functionality from C-d.  If mac/windows users
want to delete a region, they can use DEL (backspace).

Thanks,

BTW, I realize that DEL/backspace might theoretically have the same
problem, but it's also a clearly more useful binding, and for whatever
reason doesn't seem to be problematic in practice for me.

I don't know what was Chong's motivation for it, but one reason i that
the `delete' key is often remapped to C-d.

There's no DEL key on Windows, only <Delete>, which is remapped to
C-d.  Maybe the command should distinguish whether it was run by C-d
or <Delete>, and behave differently wrt the active region.

Deleting an active region with Backspace is a bad idea, IMO: that's
not how other apps behave, while this feature exists to be compatible
with other apps.

Just tried it in the location bar of firefox.  Backspace certainly does
delete an active region there.

And in any case, hitting <Delete> is a customary op, so removing it is
not a good idea.

P.S.  Note that I don't use active regions at all, so my personal
habits will not be affected either way.

This change has removed a reaonable distinction between deleting a
character (C-d) and deleting a region (C-w) which was a good thing.

Yet another bad change.

"DEL" is emacs-speak for "backspace" on typical PC keyboards.

Hmm, are you sure?  I thought Backspace was _the_ traditional
delete-a-region key on macs and windows -- it certainly is on the mac
anyway (since forever), and I'm pretty sure that's also what I use to
delete stuff when I use a windows system... (since windows derived most
of its basic keybindings from the mac, it would be ery surprising if it
weren't the same)

100% agreement.  This is truly a bad idea.  C-d (and <delete>) in Emacs should
do what it always has done: delete the next char.

[I did not realize that C-d had been changed this way, since I still don't use
Emacs 24 (while waiting for the selection stuff and other bugs to die down).  I
see now that this was introduced in thread "Updated proposal for DEL to delete
active region".  I did not see that it was part of that proposal at the time.
Most of the discussion there was about the commands and their names and mappings
and other problems about breaking compatibility.  This additional change slipped
right by me.  I wouldn't have missed it if C-d had been mentioned in the Subject
line instead of DEL.  DEL already deletes the active region in delete-selection
mode (which I use), but for C-d to do that is a real change.]

Please reverse this change.  This is a terrible design decision.

Yes, and DEL/backspace has always deleted the active region in delete-selection
mode.

That's not a reason.  That's not a reason to change the behavior of either/both
of them.

People maybe often call you "Stef" (dunno).  That's not a reason why both "Stef"
and "Stefan" should suddenly start referring to a completely different
person/behavior whenever the moon is full.

No.  Both <delete> and C-d, whether mapped together or not, should do what they
have always done in Emacs: delete the next char. Whether the region is active or
not.

Huh? That's how the Backspace key behaves in other apps on Windows, AFAICT.
(Well, "active region" is only an Emacs thing, but for Windows the selection is
deleted when you hit Backspace.)

And IE and Outlook and Word and Windows Explorer and...

Hitting Backspace in most apps on Windows deletes the selection.

+1, including for "yet another".

Emacs had the best selection/region behavior around, especially if a user chose
to use delete-selection mode.  For months now selection/region behavior has been
in the process of stumbling "improvement", leading to lots of bug reports and a
fair amount of grumbling.

Personally, I'm just waiting for this work-in-progress to die down and the final
customization settings to be made known that let users restore the previous,
sane selection/region behavior.

There are so many ways Emacs could _really_ be improved.  Why is it so hard to
learn "If it ain't broke don't fix it"?

I am trying to understand the real problem here. I personally think the 
new behavior is more intuitive, but anyway. If you mark an active 
region, why exactly do you press C-d? Wouldn't you expect the command 
after selecting the active region to be executed on the active region?

Thanks.  But we're discussing here what to do with C-d: for `delete' we
already decided that it should delete an active region (by default).
Whether you agree with this `delete' behavior is irrelevant.

Actually, C-d runs delete-char (or in 24.0.50 delete-forward-char) and 
C-w runs kill-region. I thought the difference between delete and kill 
was that the latter puts the killed section on the kill-ring, no? I 
would definitely appreciate a distinctive behavior like that.

Btw, in 23.2 (on Windows), how do I delete (not kill) an active region?

C-Space, C-f a couple of times to select word, then neither Backspace, 
nor Delete actually delete the active region. I can only kill it with C-w.

Hmm, that's quite the effort required for a simple thing like that. I

As for C-d and its command delete-forward-char, the documentation states:

To disable this, set `delete-active-region' to nil.

Imho, the default behavior is more consistent than the old behavior. C-d 
without an active region deletes the character, with an active region 
deletes the region. Makes sense to me.

I press C-d to delete the character after the cursor -- the command is
called "delete-forward-char" after all.  Adding a new meaning when the
region is activated may or may not be an extra convenience, but it's
not unambiguously natural behavior.

It's not uncommon to have the region be activated somewhat
inadvertently; this is generally harmless, but since the traditional
behavior in emacs is to simply deactivate the region when one hits
C-d, I've apparently become used to hitting C-d to perform its
traditional functionality, even when the region is active.  Because
C-d is a very low-level command, this sort of thing usually occurs in
a quick sequence of commands, not as a carefully considered event
where I think deeply about the meaning and consequence of each
keystroke before executing it.

As I mentioned, DEL/backspace theoretically suffer the same issue, but
don't seem to be a problem for me in practice; maybe that's because
I've also become used to the "extra functionality" in that case due to
using mac/windows software.

Moreover, adding this new functionality to DEL/backspace has
undeniable utility, because many many mac/windows users have that
particular usage hardwired into their fingers.  This is _not_ true of
C-d.

To delete a char, the char after point.

No, I would expect to act as it always has, on the char after point.

That also prevents DEL (Backspace) from deleting the active region.

But at least setting it to nil does not prevent DEL from working correctly in
delete-selection mode.  So yes, setting it to nil is a solution for me, since I
use delete-selection mode.

I still think this "feature" of having C-d and <delete> delete the active region
is misguided for Emacs.  But as long as it doesn't affect delete-selection mode
I cannot complain for my own use.

I do complain for Emacs, however, that the default value of the option changes
the default behavior.  If those behind this "improvement" want to let users
optionally delete the region with C-d and <delete>, then OK, provide that as an
option.  But do not make it the default.

Keep the default behavior as it was, and let users try the new Wunder behavior
optionally, if they so wish.

I see.  Where/when was that decided?

That's too bad.  C-d and <delete> should just delete the next char.

Anything I say you might consider irrelevant, whether I agree or disagree with
you.  That's your right.  I still voice my agreement or disagreement.

Voicing disagreement to your decisions is often ineffectual in terms of getting
you to reconsider, it is true.  That is not a reason to keep silent when a
choice is bad.

The "DEL deleting the region" behaviour was something that was driving
me insane.  I usually jump around a lot with `C-x C-x' in buffers, and
then I may want to delete something, and I use `DEL' to delete stuff
with.

So I just switched off `transient-mark-mode', which is something I
suspect most Emacs old-timers will be more comfortable with.

While I have some sympathy for that train of thought (there's nothing as
enraging as a trusted tool suddenly doing something unexpected), that
means that all new users have to suffer forever with an old-timey
behaviour, even though the new behaviour might make a lot more sense for
new users.

After all, experienced Emacs users know (or should know) that they can
twiddle some variables to get any old behaviour back.

I personally don't care what happens to <delete> (I never, ever, use
it), but to be fair, I think there is a case for it having the "delete
region" functionality:  (1) it seems to do that on "other" software,
and (2) It's the only key on most keyboards that's actually labelled
"delete", so it's not surprising that naive users might expect it to
delete the region they just carefully selected...

[and again, neither is true of "C-d"...]

I really like transient-mark-mode actually, and generally find the
"active region functionality" of most commands both useful and
intuitive.

C-d is not one of those commands, of course; really I think it's simply
too low-level a command, and the extra functionality not really a
natural extension of the basic functionality.

Hmm, it might be cute if the "active region" stuff was actually handled
by the key-binding lookup mechanism!

                (lambda (n beg end)

I cannot find such a decision in the mailing list.  AFAICT, the <delete> key
wasn't even mentioned in Yidong's proposal ("Updated proposal for DEL to delete
active region"), except to remove it from `mouse-region-delete-keys'.

His proposal addressed the commands, not the keys, putting the <delete> and
<deletechar> keys squarely in the same boat as `C-d' (and `DEL').

So why do you apparently consider that <delete> has been decided and cannot be
discussed, whereas the question is still open for `C-d'?  Where/when did you
decide that the <delete> key, but not (yet) `C-d', should delete the active
region?

Bzzzt!  No, but thanks for playing.

All new users will NOT have to suffer forever.  In fact, NO new users will have
to suffer forever.  New users, like old users, can discover options and change
their settings if they like.

The default behavior should be the behavior that we think is best out of the
box.  I don't happen to agree that the default behavior for C-d (and <delete>)
should be changed.

Would that it were (always). ;-)

But I am hoping and expecting that the promises of new settings to get back all
of the pre-24 selection/region behavior will be respected.  Still waiting for
the dust to settle on that one.

If new users sees a tool behaving strangely, they say "how odd", and

Indeed.  I suppose we could get away with mapping C-d to delete-char and
[delete] to delete-forward-char.  The main disadvantage would be the
breaking of the equivalence of C-d and DEL.

Some yes, but not all.  You said "all new users".

Following that logic, ALL of the Emacs default UI should be exactly what all new
users expect - nothing more.  (Let's ignore here the fact that new users do not
_all_ expect the same things.)  We should then make no attempt to move newbies
in what we think is a better direction.

That has not been the approach for designing Emacs (although some periodically
do argue for such a knee-jerk recipe).  Instead, each feature and its options

Until you delete a big bunch of text by accident.


You could (re-)bind keys to make something "simple" like deleting a
whole bunch of text for good the default for you.


The current situation is, we have to rebind more and more keys to do
something reasonable in many, many cases.  That's worse.

Why wouldn't something simple like that be available with a simple key

Consistent with what???

The old behaviour was _clever_ !



Imagine you have created an active region. Once you have done that, you
need to be really carefull how to proceed (slow down).



If you now decide to keep the region, you cannot go on with the next
natural editing command.  Instead, you must deactivate the region first,
or the text is gone (not for good, but see below).  (extra key press,
extra slot for remembering the region => slow down)

In those oh soo good "normal" applications you want Emacs to be
consistent with, any editing command will now replace the region.  Wich
is the course Emacs is going, obviously.  C-d does this already and the
rest will follow, since the newbies seem to tell Emacs what to do (to
find new users... bad intention --- this will make Emacs more "normal",
not better).

Note, that deliting just one character is a simple editing command, just
as adding one character.

Any of these simple editing commands can delete a whole bunch of text in
"normal" applications.  You might be used to that behaviour because it's
"normal", but I'm sure it caused you some headache from time to time :)


In Emacs, if you decide to delete the region, it's just pressing a `w'
instead of a `d' (or any other simple editing command).

In neither case, the region will be lost --- in Emacs.

Simple, isn't it?



Now imagine, for some reason, you have deleted the region.  A few
minutes later you recognize, it was a mistake.

Now, in "normal" apps, you press "UNDO" many many times, until you get
your region back.  You lose all the work done from deleting the region
onwards until this point in time.  This slows down editing again.  This
is stupid.  This is anoying even.


That's why we need to distinguish between commands that act on region
(e.g. `C-w') and ALL other simple editing commands, including `C-d'.




As most people here, I rarely use backspace or delete.  They're awkward
to type.  But defining them differently is a surprise, true enough.
This means the decision made was a mistake.

In 23.2 you use C-d to delete the character UNDER the cursor. Unless you 
have a different definition of cursor than I do.

delete-forward-char does not make much sense to me either. From the 
documentation the only difference to delete-char is said behavior or 
killing the active region. Technically, it's a delete backwards.

I do like the behavior though.

I usually activate the region to perform some kind of a command on it. 
If I decide that I need to delete the character under the cursor instead 
of deleting to entire region, is it too strange to hit C-g first, to 
deactivate the region and then press C-d to delete the character? That 
seems like a pretty normal workflow to me. Unless you are expecting 
implicit behavior like deactivating the region before deleting the 
character. As an Emacs user of 2 years (not 200) I wouldn't necessarily 
expect implicit (or traditional) behavior like that. ;)

Absolutely true. C-d, to me, is a convenient alias for the <delete> key, 
which on most keyboards is inefficiently out of reach. Every single 
Windows application that I just pulled up from Explorer, to Firefox, 
Chrome, Open Office or whichever, behaves the same: pressing <delete> on 
selected text deletes the entire selection. That, of course, does not 
mean Emacs must do the same, but just serves as an example that there is 
many many users who would expect this to work like they are used to.

This is NOT reasonable at all and was said too many times.



BTW: New users are NO reason for a change.  It just pure virtual and
holds no truth at all -- it cannot.

Most "normal" applications are inferior to Emacs, that's why we all use
Emacs in the end.

So how can those "normal" applications rule Emacs ????


I for one do not want to hear that virtual "new users" argument any more
on a reasonable mailing list.  It is NO argument.






Technical advantages, reasonable behaviour and preferences ARE arguments
for changes or, in this case, against them.


Deleting regions through simple editing commands is NOT reasonable.
It slows down editing and is non-productive (some say dangerous).

Here's one such old-timer.

Re: C-d deleting region considered harmful

[Richard Stallman]

    I notice that various deletion commands will now delete an active
    region.  The most obviously useful to newbies is DEL (aka backspace),
    as that's what other platforms use, and I don't have any problems with
    that (and I might even use it occasionally)

Did people go ahead with that change?  Such a change should not be made
without polling the users first.

I tried it for a few days and found it rather painful.

Likely.  Emacs has the cursor _between_ characters.  vi has the cursor
_on_ characters.  So vi has commands for inserting before and after a
character, before and after a line and so on.  Emacs has only one kind
of insertion, _at_ point.

Yes.  Maybe this helps too:

The cursor is a graphic indication of the text insertion position, aka point.
The position is unambiguous, no matter how the cursor might indicate that
position.

Typically, when the cursor shape is not narrow enough to show between two chars
it is displayed more or less on top of the char that follows the insertion
point.

A bar cursor is narrow enough to show between two chars.  A box cursor is wide
enough that it is shown in Emacs on top of the char after point.

C-g is a superfluous extra keystroke in this case.

The advantage for me is that I don't keep deleting text that I don't
want to delete.  :-)

In addition, I don't have to stomp on `C-g' for every third command I do
to make the region go away and let me edit stuff as normal.

(I think `C-g' should only be used when you really want to get out of a
sticky situation -- not as part of the normal editing routine.)

I use "C-x C-x" _a_lot_ as a kind of one-time bookmark (augmented by
"C-u C-SPC" when necessary), to jump quickly between two spots in a
buffer.  With this paradigm, the region is not really "region", it's
just a portion of text between 2 loci of interest.  Therefore, it
drives my nuts that Emacs paints the text in color each time I type
"C-x C-x", because I have no intention of marking the region, I just
want to jump.

OTOH, I always have C-w or M-w if I want to kill the region.

So I have a very good reason _not_ to use transient-mark-mode, and
none to use it.

Sebastian,
I get your point. You like the traditional way of Emacs' behavior and 
the more I read about it, the better I understand why.

However, there are no absolute truths when it comes to discussing 
efficiency in editing, since there are always personal preferences and 
habits involved. I might argue, that selecting text (with transient mark 
mode) and then replacing the text instantly with new text by inserting 
characters, like any other editor does, is a lot more efficient than 
having to kill the selection first (or let alone, delete with M-x 
delete-region!) and then inserting characters. You object, since that is 
not the way you are used to working.

Re: C-d deleting region considered harmful

Question for the people who dislike transient-mark-mode and it's
related behaviors:

Do you find yourself making an unwanted `highlighted region' using any
other method than C-xC-x?  The potential candidates that come to mind
are `C-space and movement', shift-selection, and mouse-sweep.

I used to dislike transient-mark-mode (back when it was called
zmacs-region and I was using Epoch), and disabled it along with most
of the `chrome', but at one point I intentionally tried working with
all of the bells and whistles and found it helpful except when I was
using C-xC-x often when editing code.  I spend more time editing text
these days, and much less hoping around with C-xC-x, so I just live
with the occasional distraction, but perhaps a way to invert the ARG
of exchange-point-and-mark would let more emacs hackers enjoy the
benefits of t-m-m without being annoyed by the spurious flashing/C-g.

I find `transient-mark-mode' quite useful, some of the commands work in
a different way, maybe more intuitively (for instance `comment-dwim' or
some of the replace functions).

However I've been annoyed quite few times when it highlights the region
when I don't want it. C-x C-x being a primal example (yes, I understand
that it's a change in semantics).

So I think overall it is a good improvement for handling regions in
Emacs.

However, I would not like to see C-d killing region, as in my work flow
I quite often used it with selected region (most importantly it is
better to separate C-d and backspace). Also people who are aware of C-d
most likely are people who used Emacs for some time, in a contrast to
the users who just hit backspace. So the behaviour of having a choice,
`kill or not to kill' the region with a pressure on a intuitive default
behaviour for both groups of users seems to reasonable.

Perhaps `C-x C-x' is the prime annoyance factor here?  It certainly was
for me.  Perhaps it just shouldn't activate the transient mark mode?

No, never.  I disabled transient-mark-mode a split microsecond after it
was thrust upon me.  I think most hackers who "dislike" this will have
done likewise.  By the way, "dislike" doesn't come close to how I regard
transient-mark-mode; visceral revulsion is closer to the mark and point.

I still occasionally get this ghastly effect (e.g. when I start emacs -Q
for some testing reason).  Sometime I'll get around to hacking my copy of
the place where this default is set.

I'm sure t-m-m could be made nicer.  For a start, it's a bumbling
conflation of three things which ought to be independently setable,
namely (i) Highligting of the region; (ii) a form of narrowing to the
region; (iii) disablement of some region commands.

In fact, if I could disable (i), that intrusive dark blue obliteration of
my font-lock and hi-lock highlighting, I might even get to try t-m-m.
But then, many of the config variables are so badly named
("transient-mark-mode" ought to be "transient-region-highlighting" since
the mark is no longer transient by default - all region commands are by
default executable) it would put me off even just setting these newspeak
variables.

BTW, I vote for C-d keeping its "do one thing and do it well" binding of
`delete-char', even though I might have disqualified myself from voting.
When I have to use inferior software I detest that software marking
regions without my consent and thereby forcing my right hand away from
the home position to remove this frivolous marking on pain of losing the
entire region.

In fact, I think I predicted the current confusion when the decision to
make t-m-m a default was taken.

Well, when we are typing linearly, we don't want the block cursor to be
on the character we just typed, but ahead.

I just did C-h h C-x C-q, went into the Hebrew text and typed a few
characters (like x or ( ) since ( ) are not strictly L-R).

Good question.  New thread.

If indeed most of those who are annoyed by t-m-mode (I am _not_ one, FWIW) are
_mostly_ annoyed by `C-x C-x' activating the region, there is a simple solution
for them: rebind `C-x C-x' to a similar command that never activates the mark.

Going beyond such individual remedies, are there many such annoyed users?  If so
then perhaps we should simply make that change to the default behavior: _not_
have `C-x C-x' activate the region.

`C-x C-x' currently has two independent effects that are only artificially
coupled: (a) activate the region, (b) swap point and mark.  Both effects are
useful, but they need not be coupled in the same key/command.  Personally, I
don't think I would have a problem with using two (simple) keys for those two
effects.

(We effectively already have different keys via the prefix arg, but their use is
not so convenient.  A new, separate binding for region activation would need to
be simple.)

For those who really want the current complex, DWIM behavior, we could keep it
but just not bind it to `C-x C-x' by default.

And the current behavior really does not deserve the traditional name
`exchange-point-and-mark'.  That name does not adequately describe its behavior
anymore.  Perhaps put `-dwim-' in the name somewhere, if we decide to keep such
a command at all.

Another possibility that just occurred to me (was this perhaps already
discussed?): Let `C-x C-x' activate the region only if repeated (i.e., `C-x C-x
C-x C-x').  But I suspect that that would still be annoying for navigational use
(bounce to see where the mark is).

I see the problem. Can't say I ever used C-x C-x like that. But that

No.

I never use `C-x C-x'.
I never use shift-selection.
I don't use the mouse to edit text either.

I suspect you're aware of `M-y', right?
The last kill is always on top of the kill-ring.
Keeping more than one thing for yanking is one of the unique strengths
of emacs.

Yes I am aware of that. I actually use browse-kill-ring for maximum 
convenience with the kill-ring. But I think you misunderstood: I want 
only things on the kill-ring that I put there. I don't want things to 
end up on the kill ring which weren't supposed to go there, i.e. deleted 
items. So, the solution of using C-w for deleting (not killing) a region 
is suboptimal, since it pollutes my kill-ring. I press M-y which (with 
browse-kill-ring) pops up a nice selection window and I have to sift 
through all of these deleted items instead of my nice and clean 
collection of kills.

    Thanks.  But we're discussing here what to do with C-d: for `delete' we
    already decided that it should delete an active region (by default).
    Whether you agree with this `delete' behavior is irrelevant.

It won't bother anyone for `delete' to delete the region.  Making
`backspace' do so is the change that will bother lots of users.

However a lot of other people also expect C-d to delete the visible
region. I think we really need to get compatibility of this kind
implemented. (I have some ideas for it, but I have a lack of time at
the moment so I have preferred not to say much about it.)

Not a good idea, I think, since one of the primary uses of C-x C-x is to
re-activate the region!  [for me about 90% of the time I think...]

It'd be good to have an alternate, unbound-by-default variant that
didn't activate the mark though, to make rebinding easy for those that
prefer the no-activate behavior.

But it's also the only such change that really matters for

Huh?  Where do you get that?  Who would expect that based on other applications

Start by saying something to back up your preposterous claims that a lot of
people are used to C-d deleting the selection and that there is a
"compatibility" imperative for C-d to do so.

If you just want to reactivate the region, the proper keysequence to do
only that and nothing else would be C-x C-x C-x C-x (otherwise you also
move point).  So one could make this reactivate only on second call
(like C-SPC does).  On the other hand, C-x C-x C-x C-x is often used for
checking "did I leave the mark just where intended?".

I don't even know what "re-activate the region" means, so it's not a
primary use for me.  :-)

People use `C-x C-x' for different purposes, which makes it more
complicated to satisfy everybody here, perhaps.

Re: C-d deleting region considered harmful

[Bastien]

RMS suggested to poll the users for such issues.

This was also suggested many times when the list was discussing t-m-m to
be turned on by default.

There wasn't any poll.

A poll is never an easy thing to do: you need to make a clear proposal,
you need to have a thoughtful discussion with clear arguments, you need
to be confident that enough users we participate to the poll, and you
need to take some time and energy to actually run the poll.

But besides that, is there any reason why no poll has been made so far?

This is not a rhetoric question: maybe Emacs history has shown polls are
not effective, leading to more debate and less consensus; or maybe users
don't like polls.  

But I'd be interested to understand what prevents a poll to happen.

Thanks!

That would be a circular definition, suffering from the same issue

Yes, I mentioned all of that.  But C-x C-x C-x could activate the region and
swap positions, and C-x C-x C-x C-x could do so without swapping positions.  Not
ideal, but a possibility.

(But it would be better to find a simple key that is not used or whose current
use could be sacrificed.)

Er, no.

It doesn't actually _matter_ about 90% of the time whether the point and
mark are swapped (as typically the entire point of activating the region
is to operate on the region as a unit), and I think you can see that a
two-keystroke command is preferable to a four-keystroke command...

It is also worth noting that one of the motivations for making deletion
characters act on the region was to eliminate mouse-region-delete-keys,
and hence to avoid treating "regions made with the mouse" as a special
case.

[delete] was in mouse-region-delete-keys, but not C-d.  So, if C-d
deleting the active region is especially bothersome, I think it is OK to
decouple [delete] and C-d.

Not to point the ``you're wrong!'' finger, but I suspect that this is not the 
primary use of C-xC-x for *most* people, but instead is the use for a
narrow selection of people who learned to appreciate using the active 
region with the keyboard before mouse/shift-selection was really common.

I suspect that the people (like me, admittedly) who started to really learn
emacs before transient regions had already internalized C-xC-x as `hop 
between two spots', and the newer people who are used to graphical
feedback flourishes like a highlighted active region are used to setting the
mark explicitly, or using either the mouse or shift-selection.

I suggest adding a flag to invert the default meaning of ARG in
exchange-point-and-mark, at least as an experiment.  I suspect that
the new behavior would be more in line with expected behavior for most
people, but it'd be hard to determine, and it seems reasonable to
default to the existing behavior in such a situation.

I'll see if I can put together a patch and try it out.

Good.  We're just waiting for someone to cobble up

Now for the spinoff thread that keeps spinning off other ones: I'd be

How about C-space C-x C-x (i.e. check if (eq mark omark))?  I assume
that C-x space is intentionally left unused due to some conflict or
other.

Very please to excuse me, but may be it need to stop decoupling
aliases into surprisingly different functionality?

I always used to C-d and "del" key as aliases under Emacs.  And want
to continue the same.  Just because keyboards are different.  Full
sized pc keyboard is one thing with the one distances between keys and
good separated navigation block.  Netbook keyboard is absolutely
another thing with absolutely different key sizes and different
physical keys placement.  I was (and is) very exited by these [as I
think] intentionally provided aliases that greatly improve usability.
And please, don't ruin it!

And for clearness: it's not about whether delete-char should to delete
active region (if any).  Anyway I can to turn such feature on or off
through customize or init.el.  It's about decoupling/breaking of very
useful aliases, which allows to feel comfortable under variety of
highly different keyboards.

About stop activating region by C-x C-x.  I'm (of course) unable to
speak for anyone who uses t-m-m, but for me C-x C-x, same as C-x C-x
C-x C-x is intentionally thing for activating region.  And usual goal
is to send this region to the external filter (as in C-x C-x C-u M-|).
 Just depending on goals I want to start review or editing of results
from top or from bottom and therefore use 2 or 4 C-x.  And it is
simple and logical: exchange point and mark and activate region, just
repeated twice if need (thanks to "activate" instead of "toggle"
semantics).  Now it may be transformed to exchange and some when
latter activate.  What if I hit C-x yet another 2 times?  Continue to
activate region?  Start to toggle?  Start to toggle every 2nd (even)
pair of C-x and do nothing on every 1st (odd) pair of C-x?  Something
another?

Again, please excuse me, I have no intention to insult anyone
personally or as group.  I just argue that here are many things.  And
logical consistence is not the least of them.  Just because decreases

The reason C-x C-x activates the region
is so that you can have a way to activate it
without changing it.

That is a very useful thing to do, so it needs to be short.  If C-x
C-x ceases to work, and the new method is less convenient, that is
a step backward.

I am not convinced it does.  The case in which newbies would expect
Backspace to delete the region is after mouse-selecting it,
and it already does delete the region in that case.

I think a newbie expect the visible region to be delete by backspace
always (at least I think that is the case on w32). Why don't you think
that?

It's true, that my claim is "just my claim" -- but on the other hand
so is yours (it doesn't seem any more logically consistent).  I think
actual data is necessary to actually determine which is really more
widespread.

Remember, C-x C-x _reactivates_ the region, it's not a "set the region
command", and indeed, my most common use seems to be using it after
some typing goof accidentally causes my (laboriously selected) region
to get deactivated for some reason.

For the record, I'm definitely in your generation -- I first started
using Emacs regularly in 1983.  So while I like tmm a lot, I'm of the
"keyboard generation."  I learned the "new usage" of C-x C-x pretty
quickly, and I don't see any obvious reason to believe that others
long-time users are any different (many long-time users of course,
hate tmm generally, but they probably just turn it off, and so really
don't have a dog in this race).

Just for clarity: it was about "don't activate region on 1st C-x C-x
and activate it on 2nd C-x C-x".  Reading the Chong Yidong's "C-x C-x"
e-mail hinted me that you meant replace C-x C-x binding from "exchange
and activate" to "just exchange" and introduce the new "just activate"
key binding.  Sorry for misunderstanding. :-(

No.  Newbies actually use the keyboard too, you know (even if they're
not used to Emacs)...

Anyway, having mouse-regions be "magic" is confusingly inconsistent, and
a bad UI generally.  That was a big wart on Emacs in the past.

It's obviously impossible to have perfect defaults, because we're trying
to unify a widely disparate set of user experiences into one UI.  A
change that makes things better for some often makes others unhappy.

There's little we can do other than trying to minimize unhappiness, but
at least we can (1) keep things customizable, so those that just can't
deal with a change can easily find relief, and (2) try to make Emacs' UI
broadly consistent, so that's it's at least easy for users to form a
mental-model of how things work (and easy to document)...

You can ignore the "newbie argument" if you want; I think a lot of
what's being done in their name actually applies equally well to
people that switch often between Emacs and other UIs, and generally to
the goal of having Emacs exist harmoniously in today's environments.
Maybe some people _only_ use Emacs, but I think many of us aren't so
lucky...  :)

For instance, I find having shift-selection available in emacs very
nice for those times when I happen to be flipping back-and-forth
between Emacs and another text-editing interface.  Of course,
shift-select doesn't interfere with other features, and other less
benign changes need to be approached more carefully.

[I turn on "emacs bindings" modes whenever I can (e.g. GTK and
Eclipse), but these are usually only very approximate emulations, and
one still needs to use the native bindings for many operations.]

Mostly, it's traditional and old-timers are used to it.  It took me
close to a month to get used to the various differences, then I
decided I liked t-m-m (actually, zmacs-regions) better on than off.

More scientifically, if you have an active region, then you can have
"modal" behavior: deletion operations can (implicitly) act on the
region instead of on specific text units, insertion operations can
(implicitly) substitute new text for the region, and so on.  Without
active regions, you can't have this kind of modal behavior.

The two styles are *equally* powerful.  Some people like the modal,
DWIMmish, behavior better (it can be slightly more efficient in terms
of keystroke count), while others like the non-modal, DWIS ("do what I
say"), behavior better (it's better adapted to creating personal
idioms and using "muscle memory", I think).  Much of the taste
difference can be attributed to "what you are used to", of course, and
I think that the strongest reasons for preferring one to the other are
what you are used to as "traditional" for you.

Even if i like C-d to delete region i think it's better to not activate
it as it is easy to enable that if one need it.(the contrary is not)
But i wonder why, when you enable such a thing you don't create a
variable that allow one to enable or not this feature.

It seem there is two use of C-x C-x:

1) Exchanging point and mark allow one to modify beginning or end of
region, preferably with transient-mark-mode enabled.
e.g i want to keep first five lines and 3 last lines of buffer:
C-x h C-n(* 5) C-x C-x C-p(* 2)
   
2) Without transient-m-m enabled it allow to navigate in a buffer from
one point to another what is not very useful unless you are working in
only two differents positions in buffer.
So why these users are not using C-u C-<space> with
set-mark-command-repeat-pop enabled?
I personnaly prefer using a mark-ring browser to know exactly where i
move.

So it seem all the tools are here in emacs (except mark browser) so why
do you always want to oblige people using this or that feature?

Maybe add user variable to enable this or that but keep emacs
flexibility, that allow one to do exactly what he wants with emacs.

Arguing 'this is better for Newby' remove this flexibility and will reduce
Emacs power to the level of other 'popular' softwares that is very low.

That is to be taken with a heavy grain of salt since historically
zmacs-regions and transient-mark-mode have had a number of small
differences.  Enough that some people moving back and forth used
zmacs-regions on XEmacs, but scorned transient-mark-mode on Emacs as
being unusable.

Now the latter has been in constant flux over the last versions.  I
don't know how they compare in user acceptance and semantics in the
current state.

And I don't know whether there are any Double Power Users left who could
give qualified comparisons.

I don't think that this really applies all too much for
transient-mark-mode: the complaints do not center around user interface
philosophies, but rather the nitty gritty details.

In short: figuring out for each choice the least annoying details of
operation.

Not having transient regions as sideeffects of other useful operations
at all, of course, is reasonably simple to implement.

There are not really many commands left where the setting of
transient-mark-mode should make a difference, or even a bad surprise.  I
can think of C-SPC, C-x C-x, M-< and M-> and that's more or less it.
Then there are the mark-something commands (I have my doubts they are
used very much) where the transient-region behavior would seem somewhat
less contentious.

I'm not sure what you mean. I use C-x C-l and C-x C-u on a nearly

May be :-) But I'm personally feel self very uncomfortable when don't
see what going to be changed (the region in this concrete case).  It
is similar to search&replace: it very convinient to see the "going to

C-x C-x will show you the other end of the region just fine without

True enough.  My opinions on `expected behavior' are perhaps better
described ``what I believe new users who start with modern GUI's
(Gnome/KDE/MacOSX/Winwhatever) are more likely to expect, based on a
pretty small sample size'', which is indeed `suspect' by itself.

Probably I should have emphasized the ``as an experiment'' part more.
That's my fault; I had originally intended to include a patch to try, then
something came up that caused me to not have as much time as I'd
expected so I quickly rewrote the email and sent it.  I wasn't suggesting
that we change the default for everyone and see what happens, but
it certainly could be read that way.

I'm using such a simple patch now, but I don't believe that it will do
the right thing in the face of t-m-m being enabled/disabled, so I'm
holding out for more time or for someone else to create and send a 
better experimental candidate.  At that point, I'd hope to get some of 
the list stalwarts who dislike t-m-m to potentially give it a try and see
if it's better, worse, or indistinct.

    This is not a rhetoric question: maybe Emacs history has shown polls are
    not effective, leading to more debate and less consensus; or maybe users
    don't like polls.  

I did on the order of 10 polls while I was Emacs maintainer,
and I am very glad I did.  They gave a lot of useful information.

[I seem to recall you making the point in the past that the polls are
not so much a "vote" as a way to solicit reasoned arguments from a
somewhat wider group than the regular developers.]

Of course, the Emacs user community does change, and probably is more
disparate now than it was in the past (with more people getting Emacs,
and Emacs support, indirectly through N levels, rather than directly
using emacs-help etc).

It seems like the usefulness of the results would depend very much on
the nature of the question -- e.g., the results might be a lot better
when you want the feedback of experienced long-time Emacs users (and
it's OK for the results to be heavily biased in that direction), than
when you want the opinion of the "mythical newbie" or even the average
Emacs user.

Btw, I wrote the entire Hebrew translation of the tutorial with Emacs,
using the native Windows Hebrew keyboard, and found the existing Emacs
facilities quite adequate for writing even such large and complex
document in a R2L script.

Yes, indeed.

    It seems like the usefulness of the results would depend very much on
    the nature of the question -- e.g., the results might be a lot better
    when you want the feedback of experienced long-time Emacs users (and
    it's OK for the results to be heavily biased in that direction), than
    when you want the opinion of the "mythical newbie" or even the average
    Emacs user.

What we find out from polls is whether significant groups of people
find a certain feature useful, and if so _why_ they do.
That enables us to find changes that won't cause problems for them
and avoid changes that will.

If we just speculate about this, we might be very wrong.

Yes, but I said not about "whether it's technically works or not".  I
said about my _personal_ feelings and, therefore, preferences.  I'm
prefer to see what I'm "going to eat".  And the better way for me to
see a region is to have it highlighted.
