So, apparently I had some problem when handling keys such as `F10` or `F11`.

I want to move the focus from current textbox into another textbox, but not in one particular textbox. So, I wrote some code to handle key: 

```
private void checkKeys(KeyEventArgs e)
        {
            if (e.KeyCode == Keys.F10)
            {
                buyerName.Focus();
            }
            else if (e.KeyCode == Keys.F11)
            {
                discount.Focus();
            }
        }

```

But, if I put this into individual textbox, which kinda hassle to me. Is there any method to listen key whether in global `userControl` or `textbox`?

~~**Edit :**  here's my structure that I want to ask :~~

```
Form-
    |-User Control
     |-TextBox

```
