Autofill CTRL-TAB stopped working

When entering data in a calc cell, CTRL-TAB used to cycle through values with the same initial characters. Now it just goes to the next sheet. How do I restore the old behavior?

For example, in “How to Autofill Data in LibreOffice Calc [Complete Guide]”, it says:
“If you need to see more options that begin with the same letters, you can use the following key combinations: Ctrl+Tab to move forward, or Ctrl+Shift+Tab to move backwards.”

This no longer works.

It works for me in my LO7.5.8 and in the Portable LO 24.2.0 versions.
Check the Tools - Autoinput option.

My bad. I am truly sorry. My autofill list was empty. I use the same format of a certain workbook for each year, and hadn’t yet entered some common values that would create an autofill list. I kinda expect this in January, but not mid-March. Old habits die hard.

Thank you all for your kind responses.
