Autofill with Calc

How do I get to the second, third, etc. option when entering data with autofill enabled?

The 1st option comes up alphabetically. Sometimes, I want the next. The tab key used to bring up the next option. The tab key no longer does this. Where is it now?

Example: Thomas Alan will come up before Thomas Allen (2nd) or Thomas George (3rd) or Thomas Wayne (4th)

Thanks for your attention and assistance.

Use Ctrl+Tab/Ctrl+Shift+Tab

Thanks for the quick reply!
