StaticInc here is a cut and paste example of capturing the F4 key top open another form. This should be self explanatory but if you need more help just post back.
VB Code:
Public Sub capKeyDown_KeyDown(ByVal sender As Object, _
ByVal e As KeyEventArgs)
Select Case e.KeyCode
Case Keys.F4
If sender Is txtEmp Then
Dim newForm As New frmShowEmp
newForm.ShowDialog()
ElseIf sender Is txtJobNumber Then
Dim newForm As New frmShowJob
newForm.ShowDialog()
End If
End Select
End Sub
Private Sub txtEmp_KeyDown(ByVal sender As Object, _
ByVal e As System.Windows.Forms.KeyEventArgs) _
Handles txtEmp.KeyDown
capKeyDown_KeyDown(txtEmp, e)
End Sub
