Comment # 2 on bug 983203 from Stakanov Schufter

Yes you did perfectly understand. 
I found out there is an application that can "video" the screen. I can do this,
so you can see. But where should I post it I do not know. Suse Paste can handle
videos too?

I did some thinking on this problem. Is it possible that FF (since it is based
on GTK and KDE can share a different(!) setting for the same(!) shortcut? Then
it could(!) be that somewhere there is a short-cut corresponding to
"rightclick" and a short-cut to "change input layout" that is triggered while
you are in FF. Is such a thing possible? 
How can one list all attributed short-cut in one system, including GTK and KDE
(provided they coexist in situations where a GTK based application like FF runs
in an environment)? 
Would CLI with a additional command list all FF does when asking for the
orthographic corrector? Then it also should be possible. 
The switch is happening regardless if using correction in English or in German
but it annoys only in German as you are deprived of the Umlaut feature.
