How to refer to the mainwindow class from another class.

Creating a WPF app. I have one main class where all the mainwindow controls are operated.

 public partial class MainWindow : Window
 {
     public MainWindow()
     {
         InitializeComponent();
         InitializeAPIs();
     }

 public partial class MainWindow : Window
 {
     public MainWindow()
     {
         InitializeComponent();
         InitializeAPIs();
     }

I have a different class that's called FilterManager. In this class I want to operate some data on the mainwindow as well. But I'm not sure how, what's a clean way to refer to the mainwindow from this class?

    internal class FilterManager
    {
      // Reference to MainWindow here
    }

    internal class FilterManager
    {
      // Reference to MainWindow here
    }

Practicing OOP in c#, is this logical implementation of an Interface?

    void RegisterMembership(Person person);
    void CancelMembership(Person person);
    bool CheckMembership(Person person);

        person.Membership = true;
    }
    public void CancelMembership(Person person) {

How to create a hotkey so the user can stop/pause the program.

I created a WPF app that automates mouse movements. When the program is active the user cannot press the stop button since the mouse is being used. How do I create a hotkey that can be pressed and stop the programming. I searched the internet and I found 2 options, but I don't know which is best 1. Use a side thread for the program and a main thread that listens for any hotkeys. Then the main thread either pauses or kills the side thread. 2. Use Task ? But I'm not sure how that works.
