I'm using a Keychron K2 keyboard with my Mac, and I'm struggling to disable the backlight key that changes the keyboard's lighting. This key seems to be managed at a hardware level because its keypresses do not register in Karabiner-Elements' EventViewer.
I attempted to create a custom rule in Karabiner-Elements to disable it, but without the key code, I couldn't proceed:
{
"description": "Disable backlight key",
"manipulators": [
{
"type": "basic",
"from": {
"key_code": "YOUR_KEY_CODE_HERE",
"modifiers": {
"optional": ["any"]
}
},
"to": [
{
"key_code": ""
}
]
}
]
}
It's becoming a nuisance as I often accidentally press it, causing unwanted changes to the lighting. I've checked the manual (Keychron K2 Manual PDF), but it doesn't provide a solution to lock the backlight setting.
Has anyone successfully disabled this key, or is there a known method to lock the backlight settings on a Keychron K2?
