Edmund,
Each sheet has a _Activate & _Deactivate events you can respond to.
Or ThisWorkbook has _SheetActivate if you want one central place for code.

I need an event procedure activate "Application.Calculation = xlAutomatic"
whenver the targeted sheets are selected. I have 10 worksheets in my
workbook
where the event procedure should only affect Sheet1 to Sheet6

Purpose:
This is to ensure "Application.Calculation = xlAutomatic" is always
activated even when my other procedures in Module1 exits pre-maturely as I
disable calculation via "Application.Calculation = xlManual" at the
beginning
of each procedure within Module1 (for speed). So, if my codes in Module1
exits pre-maturely (due to poor debugging), atleast I have the event to
reactivate "Application.Calculation = xlAutomatic" whenver the targeted
sheets are selected.

Also, pls tell me where should I place this event procedure. in
Thisworkbook
or where?

Thanks in advance.
