Hi group

I have a control looking like a TrackBar, a bar, with a cursor.
I need when the user push the left arrow of his keyboard, the cursor
move left until the key released.
I have overloaded the OnKeyDown method like this :

protected override void OnKeyDown(KeyEventArgs e)
{
    base.OnKeyDown(e);

    switch(e.KeyCode)
    {
        case Keys.A :
            this.SelectedBlock--;
            break;
        default:
            break;
    }
}

It work very good with the A Key, but the event for left arrow doesn't
fire !
only the OnKeyUp is fired by the Left Arrow key.

I can't implement the repetition keystroke for arrows, or control,
shift ....

However, the ListView control for exemple allow me to scroll all the
list by push the down arrow, without release it.

How to make the repetition of the left arrow key ?
Thanks
