How do i make it so it cycles trough a list on input?

so i want to make it so when i input, lets say for example "F" it cycles trough a list of either, scripts or functions, cause i want it so i can change weapons on mouse wheel up and down, and so i can change burst type when F is pressed.

You could do something like this :

 List<Weapon> weapons; // a list of weapon components
 public Weapon weapon // an accessor to get the current weapon
 {
     get { return weapons[index]; } // that returns a weapon from the list using an index
 }
 
 private int _index;
 public int index // an index accessor
 {
     get { return _index; }
     set
     {
         _index = value > weapons.Count-1 ? 0 : value; // a ternary operator to cycle through
     }
 }
 
 void Update ()
 {
     if (Input.GetKeyDown (Keycode.F)
         index ++;
 }
