PostMessage, how to send CTRL BUTTON? : <p>I'm using C#.</p>

<p>I have process file and I can send via PostMessage for example button 'W'.</p>

<p>I have idea how to make shortcut -> I want to spam each milisecond button "CTRL" (works for button "S" cuz I checked it) and then send "W" button.</p>

<p>But my problem is I don't know how to send 'CTRL" via PostMessage</p>
