Keystroke emulation (WinForms C#) with specific delay + random +-20ms delay?

Question

C++ / C#

Greetings to all, in fact, the question is in the header. I hope you can help (send a sample code).

In my program, the user presses his key in one form, after which, the code-number (int) of this button is written to a separate class, I need to implement in another class the function of constantly pressing this key (by code) with a certain delay and to it + - 20 ms through some random function to add or subtract.

Tell me how to implement it? I will be very grateful :)

1. Form1

   public void NewForm_KeyDown(object sender, KeyEventArgs e)
           {
   
               if (e.KeyCode == Keys.PageDown)
               {
                   if (Storage.IsEnabled == true)
                   {
                       Storage.IsEnabled = false;
                       StatusOnOff.BackColor = Color.Red;
                   }
           
               }
   
   
               if (e.KeyCode == Keys.PageUp)
               {
   
                   if (Storage.IsEnabled == false)
                   {
                       Storage.IsEnabled = true;
                       StatusOnOff.BackColor = Color.Green;
                   }
   
               }
   
           }

   
   
2. Form2

   private void ChooseKeyForm_KeyDown(object sender, KeyEventArgs e)
           {
               Storage.KeyData = e.KeyValue;
               this.Dispose();
           }

   
   
3. A class that stores values ​​in order to pass them through forms

   internal class Storage
       {
           public static int KeyData { get; set; }
           public static bool IsEnabled { get; set; }
   
       }

   
   
4. Class with a function (here you need to implement this function)

   class SpamKeyFunc
       {
           
       }
