Previously active cell

Question

For the code I am writing I monitor the changes in certain cell ranges to run functions and private subs. For this I use the Intersect function in the worksheet_change

Answer 1

With this code, referring PreviousActiveCell will return desired result:

Public PreviousActiveCell as Range

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Static pPrevious as Range
    Set PreviousActiveCell = pPrevious
    Set pPrevious = ActiveCell
End Sub

This works inside single worksheet. Do you need a previous cell across other sheets and workbooks?
