I had memories of Foxpro and Clipper on my mind, when I found myself in this rabbit hole.

This is hilarious to me, because times have certainly changed.

When we first started shipping Windows software the big complaint from users was the use of Tab to switch fields, while Return triggered the default button (usually Save or Close).

The change, for users used to DOS was painful - not least when capturing numbers as the numeric key pad has Enter not Tab.

Software developers either stood firm, convincing customers to learn Tab, or caved and aliased the Enter key to the Tab key. Even today I still find that option here and there in Software that's been around a while...
