@Mahdiyar what would need to be done so this script outputs null in normal state and 1 when a key is pressed? I can’t figure it out and Bing-AI wasn’t helpful on this one either.

public class Script_Instance : GH_ScriptInstance
{

  int a;

  private void RunScript(bool active, out object a)
  {
    
    a = null;

    Instances.DocumentEditor.KeyDown -= new KeyEventHandler(KeyDownEventHandler);
    Instances.DocumentEditor.KeyUp -= new KeyEventHandler(KeyUpEventHandler);
    if(active)
    {
      Instances.DocumentEditor.KeyDown += new KeyEventHandler(KeyDownEventHandler);
      Instances.DocumentEditor.KeyUp += new KeyEventHandler(KeyUpEventHandler);
    }
  }

  // <Custom additional code> 
  
  void KeyDownEventHandler(object sender, KeyEventArgs e)
  {
    if(e.KeyCode != Keys.Insert);
    a = 1;

  }
  void KeyUpEventHandler(object sender, KeyEventArgs e)
  {
    if(e.KeyCode != Keys.Insert) return;
    
  }

}
