kanade wifi toggle
kanade brightness up
kanade caffeine on 90m
kanade focus status

caffeine on returns once the inhibitor is held. focus off turns off only what on turned on and you have not changed since, so a piece that was on before stays. night-light on turns it back on as the config says: a schedule when one is set, else all day.

Note

brightness acts on the backlight, or over DDC/CI on the monitor under the focused output, as brightness.backend says. battery limit needs a battery whose driver supports charge thresholds; elsewhere it says it is unavailable. status on night-light says the mode and why wlsunset is not running, if it should be.
