Hey there, this is the first thing that comes up when I googled this topic, so here is a reply. Basically, you need to save all the important properties, for each event associated with an action, then when loading, create the object, set the properties, then add it back to the action map... if this was python I'd just pickle the object, but it isn't, so here we are.

#--- Persistence
# example myPath = "user://settings_control_action_"+ActionX.text+".json"
func save_to_disk():
    var fileX = File.new()
    for event in InputMap.get_action_list(ActionX.text):
        if event is InputEventKey:
            var toStore ={

func load_from_disk():
    var fileX = File.new()
    if not fileX.file_exists(myPath):
    while fileX.get_position() < fileX.get_len():
        var toSet = parse_json(fileX.get_line())
        if toSet["type"] == "InputEventKey":
            var event = InputEventKey.new()
            event.device = toSet["device"]
            event.alt = toSet["alt"]
            event.command = toSet["command"]
            event.control = toSet["control"]
            event.meta = toSet["meta"]
            event.shift = toSet["shift"]
            event.echo = toSet["echo"]
            event.pressed = toSet["pressed"]
            event.scancode = toSet["scancode"]
            event.unicode = toSet["unicode"]
            KeyChangeButton.text = OS.get_scancode_string(event.scancode)
