# To customise the XKB settings to suit your keyboard, modify the

# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"

# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:

# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
