If implemented this event handler overrides the default action of showing HelpBuilder. A reference to the HelpProvider is passed the first event parameter and you can do the following to override:

hp.AlternateHelpHotKeyPressed += new EventHandler(this.MyKeyHandler);

...

protected void MyKeyHandler(object sender, EventArgs e) 
{
   HelpBuilderHelpProvider hp = sender as HelpBuilderHelpProvider;
   hp.ShowHelpBuilder();  // display HelpBuilder

   // do your custom stuff
   ...
}

public System.EventHandler AlternateHelpHotKeyPressed
