In-Game Tutorial with special actions in special areas. (Shooter)

Hey, first of all I would like to say, that I'm new to Unity3D.

I'm doing a Tutorial for an Egoshooter-Game right now. The Player starts in a Building and has to do different actions. To avoid that the player is only messing around and firing any weapons which are not needed in that moment, I would like to have special areas where the player gets new Information (Audio) and also new instructions about the moves he can make (like jumping, shooting, punching etc.) So if the player has to jump on a box, the only key working is the jumpkey. When the player is on the box there will be another thing to do (jumping isn't important anymore).

Right now I did something wie Cubes, deactivated the meshrenderer, checked the Trigger, a boolean and used OnTriggerEnter. It worked that the player is only able to jump in the area of the cube. But on the platform you are jumping at is another Cube like the before mentioned where I would like to have something different than jumping, like for example punching.

How I could I do that?

Feel free to ask if my Explanation is not that good, I'm not a native english speaker.
