Input.GetKey

Description

Returns true while the user holds down the key identified by name.

GetKey will report the status of the named key. This might be used to confirm a key is used for auto fire. For the list of key identifiers see Input Manager. When dealing with input it is recommended to use Input.GetAxis and Input.GetButton instead since it allows end-users to configure the keys.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Update()
    {
        if (Input.GetKey("up"))
        {
            print("up arrow key is held down");
        }

        if (Input.GetKey("down"))
        {
            print("down arrow key is held down");
        }
    }
}
