Answer 1

edit: still using VBA send keys.

On the sheet where the data validation cell resides (assumed it is cells A1:C1 on Sheet1), put in the following code in the Microsoft Excel Sheet1 Module (the module that holds the VBA code that is related to the first sheet)

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    On Error GoTo Err1:

    If Target = Range("A1") Then
        Application.SendKeys ("%{UP}")
    End If

    If Target = Range("B1") Then
        Application.SendKeys ("%{UP}")
    End If

    If Target = Range("C1") Then
        Application.SendKeys ("%{UP}")
    End If

Err1:
    'do nothing
End Sub
