How do I enable the keyboard backlight on aspire lite AL 15 41

I purchased an aspire laptop yesterday and installed linux mint on it. The main reason for selecting this laptop was its backlit keyboard.

The backlight works when I am booting or using windows, but is always off under linux.

brightnessctrl does not list keyboard as a device

brightnessctl -l                                                                                                                                                                                                                       ─╯

The keyboard settings has the answer (keyboard -> shortcuts -> system -> hardware). There are 3 settings for the keyboard there. Just click on one under the setting, and enter whatever combination you desire.
