I'm making a shortcut program in C#. And I've done this piece of code that works, it just print ss when I press shift.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        while (true)
        {
            if ((Control.ModifierKeys & Keys.Shift) != 0)
                Console.WriteLine("ss");
            Thread.Sleep(50);
        }
    }
}

The problem is that while true is consuming 20% of my cpu so I want to optimize it (I will not increase sleep time) and it need to work from any windows focus (If I'm using another app and i press shift it have to print ss). I just want keep it reactive and decrease cpu usage. Do you know guys any tricks?

What you want is called a 'hook', in this case a keyboardhook. Search for it. – Poul Bak Jul 07 '22 at 19:19
