How do you use the force with the lightsaber?

[36 bald fat lives with parents]

It may be possible that it is a series of things not unlike the combat order system, but I cannot figure out how to use the force throw thing when you have the lightsaber equipped.

If there's more than just a button or something I'm supposed to figure out then I'm ok with not having an answer. Like unlocking something.

But if it is anything like how you have to do combination directions, gestures, or button things it might be useful to have some kind of written thing about it. Even after all the hours I have in the game I can still never get my troops to do anything but mob the battle field. So if using the force is anything like that then looks like my feeble skills are no match for the power of the dark side.

** bit of an update **

I can trigger it but I don't actually know how im doing it. It tends to get me in more trouble than I want, but it's at least somewhat reliable so that's good. I guess if you want the world to know how, feel free to list instructions. For all those who find this and don't know how to do it, I was able to without anything special that I know of.

just press and maintain trigger on left controller (if saber iin right), point left hand toward enemies, palm facing the gound. release trigger when you want the force to stop
