bug#4931: cua-selection-mode with Caps Lock turned on selects region

[Deniz Dogan]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When I have cua-selection-mode turned on at the same time as Caps
Lock, Emacs starts selecting a region when I move point as if I were
holding shift.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/home/deniz/usr/share/emacs/23.1.50/etc/DEBUG for instructions.

bug#4931:

[Deniz Dogan]

To reproduce:

1. Turn on cua-selection-mode.
2. Turn on caps lock.
3. Move point and notice how a region is being selected.

Still can't reproduce it?

Nope (you didn't specify `emacs -Q', but I assume you've tested with
it).  Maybe you've done something wrong with your .Xmodmap, or your
keyboard is faulty.

It seems that when using the arrow keys to move point, no region
becomes selected. When using next-line and previous-line for example,
the region does become selected.

I'm using an Emacs build with no special configuration on Arch Linux
if that matters.

Are you using KDE?

I was not using KDE at the time. I was using XMonad without a DE.

I see this too (Arch Linux, i3wm, no keyboard customizations that I
know of). I see characters being translated to upper case in xev as
well.

What matters for Control + letters is the state.
  1 = Shift
  2 = Caps_Lock

With Control (4), this will give 5 and 6 respectively.
