Trying to use Caps Lock as a function layer when held breaks its functionality when pressed

[ohshitgorillas]

My goal is to be able to use the Caps Lock key in two ways:

• When pressed normally, as caps lock.
• When held, it accesses a function layer that allows me to use ijkl as arrow keys.

            ],
            "type": "basic"
        }
    ]
}

this, however, simply breaks the caps lock functionality after a few seconds. I can use ijkl as arrow keys, but the regular caps lock functionality only lasts so long before it just 'breaks'.

What, if anything, am I doing wrong?

Since caps_lock requires a certain press duration, you need to modify to_if_alone as follows.

            "to_if_alone": [
                {
                    "hold_down_milliseconds": 200,
                    "key_code": "caps_lock"
                }
            ],
