Subject: 23.0.60; Different behavior in C-e and C-S-e between -nw and normal mode
Date: Wed, 11 Jun 2008 13:26:26 -0400 (EDT)

In a buffer with text, the actions:
  C-SPC
  C-n
  C-e

with trasient-mark-mode on results only in the last line being marked.
If a rectangle is being marked out, this results only in the region
from the beginning column of the last line to the end of the last line
being marked.

C-h k C-e reports:

    C-e (translated from C-S-e) runs the command move-end-of-line, which
    is an interactive compiled Lisp function in `simple.el'.

C-h k C-S-e reports:

    C-e runs the command move-end-of-line, which is an interactive
    compiled Lisp function in `simple.el'.

Though they are both bound to move-end-of-line, they have different
behaviors.  The above sequence to mark a rectangle, if done with C-S-e
instead of C-e, works as expected with the entire region being marked
as desired.

I have invoked emacs both with and without -Q and I get the same
behavior.  Interestingly, invoking emacs with -nw causes emacs to
behave normally.  There is no difference between C-e and C-S-e, and
C-e works as expected in -nw mode.

Thanks,
Paul

I can't reproduce this.  Do you still see this problem?  If so, please
provide an exact recipe, starting with emacs -Q

Yes, I still see this problem.  The above recipe *was* with -Q.

 $ emacs -Q &

 M-<     ; you're in the *scratch* buffer, so move to the top, and mark
         ; the text.
 C-SPC
 C-n C-n ; See [1]
 C-e     ; See [2]


[1] Highlighted text is currently:

 ;; This buffer is for notes you don't want to save, and for Lisp evaluation.
 ;; If you want to create a file, visit that file with C-x C-f,

with cursor on line 3, col 1.

[2] Highlighted text is currently:

 ;; then enter the text in that file's own buffer.

with cursor on line 3, column 49 (just after the '.').

M-x emacs-version claims:

  GNU Emacs 23.0.60.1 (i686-pc-linux-gnu, X toolkit) of 2008-07-07

Interestingly, this *only* seems to happen in X.  If I run emacs -nw, I
do not see the same problem.

C-h k C-e interestingly says:

  C-e (translated from C-S-e) runs the command move-end-of-line, which
  is an interactive compiled Lisp function in `simple.el'.

Whereas C-h k C-S-e saysL

  C-e runs the command move-end-of-line, which is an interactive
  compiled Lisp function in `simple.el'.

So, it *seems* somehow, that C-S-e is behaving as C-e should...
I'm not sure why C-e is "translated" from anything.  And attempts at
re-mapping in my ~/.emacs doesn't seem to work.

I was going to update my CVS today and try another build.  I'll let you
know if that does anything.

I can't reproduce it on latest CVS.  Please try with that and see if it
still occurs.  Thanks.

Wow!  I just found that I was completely wrong in my recipe for
recreating this problem.  I was saying the actions for recreation were:

 M-<
 C-SPC
 C-n
 C-n
 C-e

However, what I was actuall typing to cause the problem was:

 M-<
 C-SPC
 <down>
 <down>
 C-e

In fact, using the recipe I claimed caused the problem (C-n vs. <down>)
works exactly as expected.  But using the down arrow key results in the
behavior I reported.

My apologies.  My fingers often do things my brain is unaware of :)

I still can't reproduce this.  It's likely you have some customization
that's causing this bug; try again with emacs -Q.

That was with -Q.  Though not with C-n as previously reported, but
rather using the down arrow key.

Have you been playing with xmodmap?

More information was requested three years ago, so I'm closing this
bug.  If this is still a problem, please reopen the report.
