How to provide a keyboard shortcut to programmatically open the primitive tab drop down in WinForms TabControlAdv?

private void tabControlAdv1_KeyDown(object sender, KeyEventArgs e)
{
   if (e.KeyData == (Keys.Control | Keys.A))
      this.contextMenuStrip1.Show(this.tabControlAdv1, new Point(this.tabControlAdv1.TabPrimitivesHost.Location.X, this.tabControlAdv1.TabPrimitivesHost.Location.Y+10));
}
private void contextMenuStrip1_Opening(object sender, CancelEventArgs e)
{
   if(this.contextMenuStrip1.Items!=null)
      this.contextMenuStrip1.Items.Clear();
   foreach (TabPageAdv tabpageAdv in this.tabControlAdv1.TabPages)
   {
      this.contextMenuStrip1.Items.Add(tabpageAdv.Text);
   }
}

Private Sub tabControlAdv1_KeyDown(ByVal sender As Object, ByVal e As KeyEventArgs) Handles tabControlAdv1.KeyDown
   If e.KeyData = (Keys.Control Or Keys.A) Then
      Me.contextMenuStrip1.Show(Me.tabControlAdv1, New Point(Me.tabControlAdv1.TabPrimitivesHost.Location.X,
Me.tabControlAdv1.TabPrimitivesHost.Location.Y+10))
   End If
End Sub
Private Sub contextMenuStrip1_Opening(ByVal sender As Object, ByVal e As CancelEventArgs) Handles contextMenuStrip1.Opening
   If Me.contextMenuStrip1.Items IsNot Nothing Then
      Me.contextMenuStrip1.Items.Clear()
   End If
   For Each tabpageAdv As TabPageAdv In Me.tabControlAdv1.TabPages
      Me.contextMenuStrip1.Items.Add(tabpageAdv.Text)
   Next tabpageAdv
End Sub
