Yes: Page 30 of The Operator's Guide for IBM 3270 Information Display Systems calls it a Tab key.

   Tab also has typamatic capability that allows you to move the cursor quickly from field to field.

  The Back Tab key moves the cursor back to the first character position in an input field. If the cursor is already in the first character position of an input field, and if you press the Back Tab key, the cursor will then move back to the first character position of the preceding input field.

The software I've used has been pretty consistent about Shift+Enter meaning "new line without triggering the Enter key action" and Ctrl+Enter meaning "action" (send the message, go to the next field, etc). The behavior of the Enter key varies from program to program, but I have yet to find a program where Shift+Enter triggered an action while Ctrl+Enter did not. Which software are you using where Shift+Enter triggers an action?

(I do agree that it's hard to remember what Enter is going to do, of course. It's just Shift+Enter where my experience differs from yours).

It's the | symbol.

On later generations of IBM terminal keyboard, you'll see | on the shift-1 position, and a separate key with the broken-bar (¦) symbol. For example, on this keyboard, the broken bar is below the backspace key along with the \ character. https://sharktastica.co.uk/image?id=qhTU8QvD

The reason for the two different types of bar/pipe characters, and why the original IBM PC keyboards only had the broken bar on the keyboard, involves a particularly arcane footnote of history relating to supporting the PL/I language on ASCII terminals: https://www.os2museum.com/wp/a-wunderbar-story/

Microsoft could implement the "Am I doing it wrong?" check via the shell script `/bin/true`

OS/2 1.0 and the first edition of the CUA were both released in December 1987 according to Wikipedia; Raymond's story isn't dated but could've happened before this. (If I had to make a wild guess, I could imagine this request was a side effect of some internal IBM battle about what the CUA should dictate).

> “a brilliant stroke of genius the likes of which the world is not likely to see again. If that one guy hadn't been born, we would have gone thousands of years with no method”

But that’s not the criteria for granting a patent. It doesn’t have to be a stroke of genius. It can be something that many people could invent at the particular moment of the filing (as evidenced by many cases of near-simultaneous patent filings, like Daimler and Benz competing for the ICE in the 1880s). It just needs to be demonstrably novel.

I’m not saying tabbing back and forth through dialog fields qualifies, but then again it’s hard to place oneself in 1980.

Err... wasn't your post a perfect example of why patents exist?

The concept probably has a real name, I call it first mover disadvantage. It is much easier to copy a mechanism than to invent it. So why even try? Every thing you have to spend real effort to invent is trivially copied the instant you try to sell it. And them copying it don't have to bear the nearly the R&D expenses you did. so it is trivial for them to sell this mechanism for less meaning you don't even get a fair slice of the pie.

So to try and limit this imbalance we invent a legal fiction, ownership, not of a physical thing, but the way it works. Not forever, but for 20 years you get ownership over those works.

Patents do have their problems, But I think the core idea is sound, create a registry of mechinisms, use this to provide economic protection to the inventor.

> A usability feature that your users cannot use or know about doesn't increase usability.

Cannot is maybe doing a lot there. There's plenty of usability features that aren't really obvious or apparent unless you look very closely. Ex: pinball machines have timed shots, but there's almost always a grace period so if you contact the ball with your flipper around when the timer hits zero and it makes the shot, chances are you'll get credit for it even though the timer expired. That's a usability feature most users won't ever notice. At WhatsApp, I would never send an S40 user a verification code where the 4th digit was 8, because if you got a text message with 123-890, s40 would turn -8 into an 8th note emoji; until today, probably 3 people knew that ... but it dramatically improved usability.

> Even though the idea isn't obvious, the implementation is. If you disclose your brilliant idea, everyone will copy it and your advantage in the marketplace will be transitory.

> So... what is the purpose of giving you a patent? That cripples the marketplace, but it fails to realize the benefit of patents, publication. Publication necessarily had to happen anyway.

If I had gotten a patent on the 'avoid -8 in verification codes', then the technique would have been public for everyone to see. So publication for exclusivity / forced licensing is an exchange of value between society and the inventor. Of course, avoid -8 is pretty obvious, when someone testing the s40 client complains about getting an 8th note in their verification code message, you make a quick tweak to code selection to avoid sending those.

For an invention that must be disclosed to be used, society isn't really getting anything in return for exclusivity. Maybe promotion of progress, theoretically, I guess, in that whoever thinks of it first gets paid; leading more people to think about things?

> move between input fields in a software form

IBMs earliest block mode terminals with field entry, including the 3270, predate the microprocessor. They were fully implemented with fixed hardware control.

IBM also infamously patented the XOR cursor.

Presumably it's to give you an advantage for putting in the work to develop it for a period of time.

> the benefit you get from coming up with this idea is that you can publish it for the world to see, and that's the only way you can benefit from it

That’s your opinion, but it’s not the spirit of the law. I’m personally fully against Intellectual Property, including for movies and music, for reasons that are obvious (public money is being spent aimlessly trying to prevent two private individuals from copying things that are copied by their very nature of being published - or trying to prevent people from using ideas that are contagious - what next, put a copyright on political ideas? on dance moves? on beautiful colors?) but that’s not the law.

> we would have gone thousands of years with no method

There are other methods: The 4 arrows. The tab method is much more efficient and easy to implement, but we would have gone with the 4-arrows-to-navigate-fields method.

You can say the same about swipe to unlock and that had been litigated to death.

Do you remember what the official definition was? I admit I was working at an internship in FEIS (Field Engineering Information Services) in Colorado and people with that title would occasionally yo-yo in to a meeting make some comment that didn't apply and then yo-yo out again. None of the engineers in the organization had anything but disdain for them. If you were late 80's, I was interning in the late 70's so its entirely possible that they restructured the job responsibilities somewhat. But again I'd really love to see what was the official job description from the time.

"To be fair, Microsoft & Bill Gates are bad at quality user experience."

In some ways. Gates deserves never-ending enmity for plaguing us with backslashes in paths. But in others, Microsoft advanced the state of UI and UX more than anyone else in the '90s.
