How to install a correct Swiss German keyboard layout

["Roland Wegmann" <rowe_gnu@gmx.net>]

Hello

I can't find the symbols ~ or @ on my keybord (console and X). In X I
have installed the german keyboard because I didn't find the swiss german
version. And as far as I can remember I also installed a german keyboard
on the console.

But now I realize that it wasn't a good idea, because it causes trouble
to use scp ...@...:/~... or to write emails ...@... .

So, how can I correct this on my iBook?

Thanks in advance for helping me
