C# Is it Possible to Set Hotkeys in C# for a Program to Run in the Background?

The discussion centers on implementing global key bindings in a C# program that performs automated key presses and mouse actions. The user seeks a method to bind keys, such as Alt + F2, to start and stop the program, even when the application window is not active. They express confusion over existing solutions, particularly regarding the use of the PreviewKeyDown event, which only triggers when the control has focus, indicating that it won't work for global key detection. The user highlights the need for a more user-friendly approach to stop the program, as relying on mouse movements could lead to complications for less experienced users. Suggestions for achieving global key bindings are sought, emphasizing the importance of a straightforward solution to enhance usability.

I have written a program in C# which presses some keys and do some mouse movements and clicks
Now i want to bind a key to my start and stop buttons (works even if window is not the active window)
I searched in google but got confused . Isn't there any easy way to do this (for example i want Alt + F2 to stop the program)
And also i saw something like this and it didnt work (unless button1.PerformClick(); is the wrong command for hitting a button)
private void Form1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
{
if (e.KeyCode == Keys.F8)
{

}
}

Unless the window is active, I don't believe that it will respond to keypress events. The description for PreviewKeyDown (https://msdn.microsoft.com/en-us/library/system.windows.forms.control.previewkeydown(v=vs.110).aspx) says (emphasis added), "Occurs before the KeyDown event when a key is pressed while focus is on this control."

I'm pretty sure that whatever window is the one that is active is the one listening for key events.

Any other easy way i can do this ?
Because it will be annoying to stop the program with a mouse movement process (especially for simple users they might force restart their computer to stop it :D )
