check if Ctrl-Key is pressed...

Hello

My problem is the following:

I want that if I press the CTRL-Key that label1 should show "Multiple Selection possible"

I have this code:

    Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
        If e.KeyCode = Keys.ControlKey Then
            Label1.Text = "Multiple Selection possible"
        End If
    End Sub

And that is working but if I place a textbox on the form and the textbox has focus it is not working anymore...
I know that I could code this for every textbox too but can I not use this as main Form event which is overriding all other inputs?

Thanks a lot

Sven
