Keyboard character setting in FC3

[Markus Huber]

Hello,

I would like to change the setting of a keyboard character and googeling 
did not really help me.

What I've got:

FC3 actual patchlevel
Language German
Gnome
Keyboard: standard hungarian (105 keys)

This runs perfectly, but I want to change one "little" thing.

At the moment I have:
AltGr+a = æ
AltGr+A = Æ
AltGr+e = nothing
AltGr+E = nothing

I would like to change the behaviour to e.g.:
AltGr+e = ä
AltGr+E = Ä

At the moment I use the Character Tool (or how ever it is called in 
English) in the panel and copy/paste these characters into texts, but I 
would prefer the convenient way through the keyboard.

Here some system informations:

$ uname -r
2.6.11-1.14_FC3

$ cat /etc/sysconfig/i18n
LANG="de_DE.UTF-8"
SUPPORTED="de_DE.UTF-8:de_DE:de"
SYSFONT="latarcyrheb-sun16"

Thank you and regards
