cua-mode and long key sequences

cua-mode and long key sequences

[mopi]

There is some special cases in cua mode that I want to improve. I'm
sure this has already been solved several times already so I turn to
the Emacs wizards in this group.

Consider the following:
1. Mark a region.
2. Type C-c and press the home button.

What I want to do is copy the region and go to the beginning of the
line. Instead of this Emacs helpfully greets me with "C-c <home> is
undefined". I understand the reason for this but I'm sure it's
possible to make it do what I want.

I have looked in cua.el but it isn't that clear to me what command C-c
sends.

The key sequences I want to modify is
C-c <home>
C-c <end>
C-c <next>
C-c <prior>
C-x <home>
C-x <end>
C-x <next>
C-x <prior>

Any suggestions or pointers to further reading?

Thanks
mopi.

Please try the Emacs 22 beta. It looks to me that CUA mode does what you 
want there.

I'm using the latest (unpatched) cvs version from
http://www.ourcomments.org/cgi-bin/emacsw32-dl-latest.pl. It is dated
20070409 so that is pretty new. Do you think I need an even newer one?

Eh, no. I myself always use the patched version, but that should not 
matter here.

I guess I am misunderstanding you then. If I press C-c when a region is 
marked and I have cua-mode on (as always) then the highlighting of the 
region disappears. Does not that happen for you?

Well, yes. Sort of.
The region will disappear if I wait a little (very little) and it will
work as expected when I then press the Home key. But if you press the
Home key too fast after you have done C-c Emacs interprets it as a key-
sequence instead of two different commands.

I don't want to slow down my typing but I'm sure there is a way to
redefine what the C-c <home> et al key sequences do.

Wow, I never noticed that! I think there is a timeout you can set in 
cua-mode for this.

Does this patch give the desired result?

This solved it (after I byte compiled the patched file)!

Thank you.

Kim,
I see that you are the original author of cua-mode. Will this change
make it into the main source tree of emacs?

Is there an easy way to include this (cvs-diff output?) as a patch?

You must be extremely fast moving from c to <home> :-) 

To me it is the other way around. If I am too slow so cua-mode reads
C-c pause <home> as C-c <home> 
whereas 
C-c <home> is copy-region-as-kill goto-char 1

It is too late for Emacs 22.1 - 

I will reconsider the change for Emacs 22.2 / 23.1

That's odd.

Is that only for C-c home, and it is with or without the patch?

Is this with Emacs 22?  On which platform?


Does is also happen with

emacs -Q
M-x cua-mode RET

Otherwise, you hve made some local customization to 
cause that behaviour.  If so -- which ?

Create in GNU Emacs a file in emacs/lisp, let's call it cua.patch,  
and keep it open in buffer. The Diff menu invites you to "Apply  
hunk." At least in CVS versions. You can delete the patch file now.

Then byte-compile the patched ELisp file or make a new bootstrap and  
install.

Yes, I see now. I don't really know what happened and I can't do it
again. My reply to mopi is just wrong. 

In fact I don't see the behaviour mopi describes at all.
C-c copies when I have marked a region. C-S-c is a prefix. 

My emacs is:
This is GNU Emacs 22.0.92.1 (i386-mingw-nt5.1.2600)
 of 2007-01-12 on LENNART-69DE564 (patched)

Regards and sorry for the confusion.
