accidentally changing keyboard layout

accidentally changing keyboard layout

[ernest]

Hi,
Recently, I've been compelled to use the Windows (XP) operating
system.
The problem I have is that every now and then I change emacs's
keyboard
layout by accident. Usually it switches to US layout, some times to
other
layouts. It must be some combination of keys, I still haven't figured
out which ones. Once it's changed I cannot fix it or I don't know how
to fix it.
I select the default keyboard layout or the Spanish layout on the
menu, but
nothing happens. I have to restart emacs every time!
Any idea how I can avoid this? This is specific to emacs, other
programs
are not affected. I also use emacs on GNU/Linux and never had this
problem. Cheers.

You are probably pressing and releasing shift+alt, which switches
keyboard language. Do that again to switch back. You can disable this
key combination in windows' control panel.

The same thing happened to me after a particularly long session. It was 
definitely caused within emacs, not by windoze, and the correct 
keymapping was restored on restarting emacs. If it happens again I'll 
try to track down the cause and report back, though I'm rather hoping it 
doesn't happen again.

For disabling Windows lang layout key binging I use such .reg file:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Keyboard Layout\Toggle]
; The value 1 specifies that LEFT ALT+SHIFT switches locales.
; The value 2 specifies CTRL+SHIFT.
; 3 disables the key sequence altogether.
; I decide use AutoHotkey to switch locales.
;
; These customisations have affect at least after logout/login.
"Hotkey"="3"
"Language Hotkey"="3"
"Layout Hotkey"="3"

In Emacs I switch to Russian by C-\. In other apps I use
AutoHotkey script:


; For lang codes see ("Locale identifier" column):
;   http://msdn.microsoft.com/en-us/library/ms776294(VS.85).aspx
; You must dublicate code.
#1:: SendMessage, 0x50,, 0x04090409,, A ; английский
#2:: SendMessage, 0x50,, 0x04190419,, A ; русский
#3:: SendMessage, 0x50,, 0x04220422,, A ; украинский

~LWin UP:: return

; Local Variables:
; coding: windows-1251-dos
; comment-start: "; "
; End:


which I wrote because Emacs key binding conflict with Windows ((.
And Windows don't allow any other key binding for switching
lang layout rather than Alt+Shift/Ctrl+Shift.

No I type left Win key + 1 to switch to EN lang,
lWin + 2 to RU lang, etc...

What makes you so sure of that?  The keyboard layout is under control of the operating system, not Emacs.  And any similar feature within Emacs (such as viper-mode) is not easily triggered.

Emacs was the only application affected, and closing and restarting it
(without changing any windoze settings) cured the problem.

BS.  Keyboard layout is per-application (at least on Win7).

Just make the layout visible on the taskbar - then you can use mouse
to switch back if it got accidentally mis-set.  I think it is called
the "language bar" or some such...

Hope this helps,
Ilya

I've worked out now what happened. I'd been using M-% a lot, and didn't 
press the 5 in time to avoid windoze catching it and switching the 
language instead. (Probably trying to do it one-handed.) The console I 
checked it against is a wrapper around the command prompt which isn't 
affected by the language change. Two gotchas in one evening. We live and 
learn. Eventually. :-)

It was that. Alt+Shift switches to US layout. Pressing Alt+Shift again
switches to another layout, And pressing again switches back to the
original layout.
Thank God I've found out, it was driving me mad :)
