Excel 2003

I take it there's no way VBA method to access control of the
AutoCalculate feature in the status bar that shows avg/sum/etc upon
selecting cells of numbers... right?

I wanted to create a button that would make it toggle from sum to avg
instead of the conventional right-clicking it and then choosing the
function manually.

If not, I'm thinking of making my own display such as a modeless form
or toolbar.

Any experience with this or any ideas?

Thanks,
Melina
