multiple mdi childs of the same form question

[markman]

How do you jump between mdi childs? I loaded them with this:

Public Sub CreateNewDocument()
    Static DocCount As Long
    Dim frmDoc As frmDocument
    Set frmDoc = New frmDocument
    DocCount = DocCount + 1
    frmDoc.Caption = "Document " & DocCount
    DoEvents
    frmDoc.Move 0, 0
    frmDoc.Show
End Sub

and now, say when I hit command1, I want the one that says document3 to come to the front. How?
