Answer 1

Use mouse_event or keybd_event. They say not to use them anymore but you don't have to find the window at all.

using System;
using System.Runtime.InteropServices;

public class SimulatePCControl
{

[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void keybd_event(uint bVk, uint bScan, uint dwFlags, uint dwExtraInfo);

private const int VK_LEFT = 0x25;

public static void LeftArrow()
{
    keybd_event(VK_LEFT, 0, 0, 0);
}

}

Virtual Key Codes are here for this one: http://www.kbdedit.com/manual/low_level_vk_list.html

Also for mouse:

using System.Runtime.InteropServices;
using UnityEngine;

public class SimulateMouseClick
{
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);
//Mouse actions
private const int MOUSEEVENTF_LEFTDOWN = 0x02;
private const int MOUSEEVENTF_LEFTUP = 0x04;
private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
private const int MOUSEEVENTF_RIGHTUP = 0x10;

public static void Click()
{
    //Call the imported function with the cursor's current position
    uint X = (uint)0;
    uint Y = (uint)0;
    mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);
    Debug.LogError("SIMULATED A MOUSE CLICK JUST NOW...");
}

//...other code needed for the application
}
