ArgumentException: Input Button right is not setup.

Whenever I try run a camera movement code:

using UnityEngine;
using System.Collections;

public class CameraMovement : MonoBehaviour {
	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
		if (Input.GetButton ("right"));
		{
			transform.Translate(Vector2.right * 5 * Time.deltaTime);
		}
	}
}

I come up with this:
ArgumentException: Input Button right is not setup.
To change the input settings use: Edit → Project Settings → Input
CameraMovement.Update () (at Assets/MyStuff/Scripts/Camera/CameraMovement.cs:12)

But horizontal axis is set as positive is right:

Plus in other cases the camera just moved without me pressing right arrow key.

The name of the button is actually “Horizontal” and it is set up as an axis so to use it you would call Input.GetAxis( “Horizontal” ) which returns a number with left being negative and right being positive. To get the right button call Input.GetKey( KeyCode.RightArrow );
