How to use the "Form" option in "Views"

Note - This relates to the Mac version

I'm confused about the purpose of "Form" when you click on the "New View" selection.

My expectation is that I can create a form in which I choose the fields and how they are displayed but it appears that is not the case. I found that creating a view as a form and then selecting the fields to appear in the form does nothing. I click on the newly created Form and I get tabs that display previously created forms. No sign of the form I expected to see.

I can't see an explanation for this in the manual, which appears to be out of date.

I'd appreciate any clarification anyone can provide.

Thanks.
