I haven't seen this posted anywhere else, so here is how to access the Actions Panel from your jsfl files. The flash object property for the Actions Panel is fl.actionsPanel. I documented all the functions and their descriptions I was able to find here:

Attached is a simple example mxp file and source fla. This example creates a panel under Window>Other Panels>Actions Explorer. The Actions Explorer window will search through the open Actions window and find the word "function". Then you can click on each line in the Actions Explorer to go to that function in the Actions Panel. I know this could be developed more but I haven't had the time yet. Hopefully posting this will help someone else create a cool tool for the actions panel
