How to make mac go to sleep with holding down a key with Karabiner? - karabiner

Question

I'd like to make a complex modification that makes macOS to go to sleep when I holding the F6/☾ key.
The following config is working BUT when I release the key that wakes up the OS instantly.
Maybe it can be combine with to_after_key_up but can't find it how to do it.
{
"description": "Map F6 (Do Not Disturb) to Cmd+Opt+Eject for Sleep Mac",
"manipulators": [{
"from": {
"key_code": "f6"
},
"type": "basic",
"parameters": {
"basic.to_if_alone_timeout_milliseconds": 250,
"basic.to_if_held_down_threshold_milliseconds": 1000
},
"to_if_alone": [
{
"key_code": "f6"
}
],
"to_if_held_down": [
{
"repeat": false,
"consumer_key_code": "eject",
"modifiers": ["left_gui", "left_alt"]
}
]
}]
}

Can't find a solution to the key releasing issue so as a workaround I'm created one with double press the F6/☾ key for same functionality:
{
"description": "Map 2x F6 (Do Not Disturb) to Cmd+Opt+Eject for Sleep Mac",
"manipulators": [
{
"type": "basic",
"conditions": [
{
"type": "variable_if",
"name": "sleep",
"value": 1
}
],
"from": {
"key_code": "f6"
},
"to_after_key_up": [{
"repeat": false,
"consumer_key_code": "eject",
"modifiers": ["left_gui", "left_alt"]
}]
},
{
"type": "basic",
"from": {
"key_code": "f6"
},
"to": [
{
"set_variable": {
"name": "sleep",
"value": 1
}
}
],
"to_delayed_action": {
"to_if_invoked": [
{
"set_variable": {
"name": "sleep",
"value": 0
}
},
{
"key_code": "f6"
}
],
"to_if_canceled": [
{
"set_variable": {
"name": "sleep",
"value": 0
}
}
]
},
"parameters": {
"basic.to_delayed_action_delay_milliseconds": 200
}
}
]
}
The reason I wanted to differentiate against single F6 press is that I'm using it in file explorers to move files between panels.
