Adding Sneaking to FirstPersonController

I'm using the first person controller that comes with Unity 5, but I want to add some things. The main one being sneaking, which will make the player move slower and make the steps be further apart than when walking. Basically opposite-running.

Problem is, I have no idea how to do this in C#. I only work in Javascript. I know, I know, people keep saying C# is superior, but I like Javascript. So can someone tell me how to do this? Or maybe point me to a Javascript version of the first person controller? Haven't found one myself.

 

I think the standard controller fps has the function that when you run in a direction and hold down shift it runs. Just find the code related to the shift action and make it a lot slower.

 

I really should start removing threads when I answer them myself... I figured out how to connect a Javascript to the standard FPS script and I've solved this problem on my own. I was just too lazy to update this to let people know I didn't need help anymore since I thought it has already vanished into the ocean of unanswered questions.
