The custom keyboard layout I use on my work PC. Modified US layout that swaps Z and Y and adds ä, Ä, ö, Ö, ü, Ü and ß to AltGr + A, O, U and S.
To use, move or copy custom
into /usr/share/X11/xkb/symbols
. Then edit /usr/share/X11/xkb/rules/evdev.xml
and add the following XML at the end of the <layoutList>
block:
<layout>
<configItem>
<name>custom</name>
<shortDescription>encstm</shortDescription>
<description>English (US, custom)</description>
<languageList>
<iso639Id>eng</iso639Id>
</languageList>
</configItem>
<varianlist/>
</layout>
