Thanks it worked!

Can I ask you another question?

I've created a custom symbols file like this:

partial modifier_keys
xkb_symbols "test_mapping" {
    ...
    custom mappings...
    ...
};

This file is located in "/home/quidh4/.xkb/symbols/test"

How can I load that configuration without loosing other keys?

I tried this command "setxkbmap -I$HOME/.xkb test -option test:test_mapping"
but I had to reboot my system because I lost the gb layout for other keys,
and they became dead keys.
