Here is some VBA top do it

Dim oldCell As Range

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Row 50 Or Target.Column 22 Then
If Not oldCell Is Nothing Then
oldCell.Activate
Else
Me.Range("A1").Activate
End If
Else
Set oldCell = Target
End If
End Sub

'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.
