My laptop has a keymap /usr/lib64/udev/keymaps/samsung-90x3a:

0x96 kbdillumup         # Fn+F8 keyboard backlit up
0x97 kbdillumdown       # Fn+F7 keyboard backlit down
0xD5 wlan               # Fn+F12 wifi on/off
0xCE prog1              # Fn+F1 performance mode
0x8D prog2              # Fn+F6 battery life extender

And it works:

leho@s9 ~ $ [git:master+?] sudo input-events 4
/dev/input/event4
   bustype : BUS_I8042
   vendor  : 0x1
   product : 0x1
   version : 43841
   name    : "AT Translated Set 2 keyboard"
   phys    : "isa0060/serio0/input0"
   bits ev : EV_SYN EV_KEY EV_MSC EV_LED EV_REP

waiting for events
00:07:32.631989: EV_MSC MSC_SCAN 28
00:07:32.631995: EV_KEY KEY_ENTER released
00:07:32.631997: EV_SYN code=0 value=0
00:07:38.247388: EV_MSC MSC_SCAN 151
00:07:38.247394: EV_KEY KEY_KBDILLUMDOWN pressed
00:07:38.247396: EV_SYN code=0 value=0
00:07:38.247416: EV_KEY KEY_KBDILLUMDOWN released
00:07:38.247417: EV_SYN code=0 value=0

But what tools do I use with i3 to assign these keypresses to some script actions? gnome-settings-daemon takes care of it for Gnome, but I prefer not to run it inside i3.
