# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))

#    Option    “XkbDisable”
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#    Option    “XkbModel”    “pc102″
# 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:
#    Option    “XkbLayout”    “de”
# or:
#    Option    “XkbLayout”    “de”
#    Option    “XkbVariant”    “nodeadkeys”
#
# If you’d like to switch the positions of your capslock and
# control keys, use:
#    Option    “XkbOptions”    “ctrl:swapcaps”
# Or if you just want both to be control, use:
#    Option    “XkbOptions”    “ctrl:nocaps”
