I did in the ThirdPersoncontroller clicked on the menu Window > animator and created new empty state called it Walk. Then i set the Walk to be default so now when running the game the character is walking automatic all the time.
Now i want to add a c# script that when i click on some key for example S the character will stop walking.
If i click S again or other key the character will continue walking from the same point it was stop.
This is a screenshot of the ThirdPersoncontroller Window Animator:
