"Status" indicators
 

I am wondering if anyone has any suggestions as to how I
might add some status indicators, somewhere on the Excel
menu bars (ideally at the bottom). I am looking to
replicate the built-in functionality that tells you, for
example, that Num Lock is On, or that you need to
Calculate, etc., etc. It would be helpful (for various
reasons) for me to be able to show whether the open
worksheet has links to any other worksheet (without going
to the drop down menu), whether calculation is automatic
or manual, and so on. Ideally a generic approach, with
underlying macros that test the condition whose status I
want to show, is what I am looking for. Hopefully, this
makes sense!
