WPF windows forms host keyboard events

This is probably a simple question but i've been unable to find a quick answer.

I have a WPF application which has a Windows Forms Control hosting a GeckoFX component (doesn't really matter).

What i want to do is capture key down events inside the Windows Forms Control and grab focus of a WPF control for some particular key combination. And what if i want to capture events from the entire WPF application window (even inside the Windows Forms Control)? I tried handling the KeyDown event and PreviewKeyDown event but to no avail.

What i want to know is if this is possible and how this should be done. I can post some code if required.

The KeyDown even on the Form should work for non special keys (like arrow keys). Use PreviewKeyDown to capture those, or use this solution.

For GeckoWebBrowser specifically, I had to use PreviewKeyDown. Also, I added a line so it doesn't break in design mode:

private void webBrowser1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e) {
  if (DesignMode) return;
  if (!e.IsInputKey && e.Control && e.KeyCode == Keys.S) {
    DoStuff();
    return;
  }
}
