You could try the elemental "Go To".

Select the range (or the entire sheet) that you'd like to examine.

Hit <F5,
Click on "Special",

Then, click on <Formulas <OK to have all formula cells highlighted,
OR ...
Click on <Constants <OK, to have the other data cells highlighted.

I have a column where most cells are based on a formula; but from time
to time I would override selected cells with a plain number.

Is there a way to automatically show (say with a shading) which cells
in a column are based on formulas and which cells are directly entered
numbers (the ability to do either one is sufficient, but I'd like to
know how to do both) ?

Thanks in advance - its amazing how much help one gets in this ng.
