My worksheets don't auto complete as I type text into cells. I have not (knowingly) turned that off. It seems to be the same for all workbooks.

Googling yields . . . "Click the Microsoft Office Button, and then click Excel Options".

I don't see Excel Options. I only see New, Open, Save, SaveAs, Print, Prepare, Send, Publish, Close

Right clicking gives toolbar & ribbon choices.

I'm using Windows 10 and Excel 2007.

Maybe I've gone brain-dead . . . I don't understand the "Code Tags" instructions above.
