Create a shortcut with two actions

Please save the code below in a .jsfl file and test it. If it works, you can place this file in the commands folder and assign a shortcut to it.

var dom = fl.getDocumentDOM();
var tl = dom.getTimeline();
var currentLayerIndex = tl.currentLayer;
var currentLayer = tl.layers[currentLayerIndex];

if (currentLayer.layerType === "folder")
{
	tl.expandFolder(true);
	tl.setLayerProperty("locked", true, "all");
	tl.setLayerProperty("locked", false);
}
