A typical use case is to swap WIN and ALT keys. A suggested udevmon job configuration for this is:

- JOB: "intercept -g $DEVNODE | swap-keys KEY_LEFTALT KEY_LEFTMETA KEY_RIGHTALT KEY_RIGHTMETA | uinput -d $DEVNODE"
  DEVICE:
    NAME: Apple Inc. Apple Keyboard
    EVENTS:
      EV_KEY: [KEY_LEFTALT, KEY_RIGHTALT, KEY_LEFTMETA, KEY_RIGHTMETA]
