What does `console-setup/ask_detect` in a preseed config do?

Question

I can't find anything on ask_detect in any of the man pages for setupcon and almost all my search results are examples of preseed files with it set to false; nothing useful at all.

What does it actually do?

Answer 1

Finally found an answer via some Ubuntu docs. It disables the dialogue asking whether the installer should attempt to (sort of) automatically detect your keyboard code by making you press a few random keys.
