Check out Home - a sample of custom launcher. Here's a dispatcher of key events inside it:

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    if (event.getAction() == KeyEvent.ACTION_DOWN) {
            ...
            case KeyEvent.KEYCODE_HOME:
                mHomeDown = true;
                return true;
        }
    } else if (event.getAction() == KeyEvent.ACTION_UP) {
        switch (event.getKeyCode()) {
            ...
            case KeyEvent.KEYCODE_HOME:
                if (!event.isCanceled()) {
                    // Do HOME behavior.
                }
                mHomeDown = true;
                return true;
        }
    }

    return super.dispatchKeyEvent(event);
}

You can implement your own behavior where the comment says. In case of this sample it would be hideApplications() call to hide the application grid.
