I'm very new to scripting in Unity, I'm trying to create a button, and once clicked it needs to simulate the 'F' Key being pressed (To pick up an item)

Here is the current code I have, I've looked all over unity forums before writing this but couldn't find anything that worked.

Code:

```cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Collections;
public class button : MonoBehaviour {

    public void ButtonToClick(int clickToButton)
    {
        SendKeys.Send("F");
    }
} 

```
