Where KDE4 stores menu configuration
 

Does anybody know where Kde4 store user's menu configuration?
I'd like to backup my menu config. I took a glance at $HOME/.kde but couldn't find it.

How about ~/.kde4?

Andrew,

Thanks for your answer.
In Debian kde4 dir. seems to be .kde.
I had to regenerate all config because my numeric keyboard had stopped working for some reason. So I wanted to keep my kickoff configuration.
I did it by copying my old $HOME/.kde/share/config/kickoffrc. That worked ok. Also moving $HOME/.kde/config dir and generating it again fixed the numeric keyboard problem.

I think in a "normal" situation copying the whole .kde to another user or keeping it as backup should work.
