Assign Function Keys to buttons

I have a form with 3 stopwatches on it.  Each one has a stop/start button.
I need to map function keys to each of the stop/start buttons.  
F1 would go to the first stop/start button, F3 would go to the second stop/start button, F5 would go to the 3rd stop/start button.
The form will be the active form, but it is likely that nothing will be selected on the form.
How would I map these function keys to the buttons?
Please provide code samples.  When I click on links my IE crashes.
Thanks

Hi, you can do something like this:
    Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        Select Case e.KeyCode
            Case Keys.F1
                ' call the 1st
            Case Keys.F3
                ' call the 2nt
            Case Keys.F5
                ' call the 3rd
        End Select
    End Sub
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.KeyPreview = True
    End Sub

You can use IsRunning property to identify if the stopwatcher is running and start or stop it.

        Dim myStopwatch As New Stopwatch
        If myStopwatch.IsRunning Then
            myStopwatch.Stop()
        Else
            myStopwatch.Reset()
            myStopwatch.Start()
        End If

Do you want to answer a question about laying out windows forms in a MDI app. Users will select from a list, not from a menu bar.
If you want to, I will post the question now.
