IBM didn't want Microsoft to use the Tab key to move between dialog fields
Some bureaucrats at IBM (business model: 'Uber for seven layers of pointless escalation') spent a VP's afternoon opposing the Tab key for dialog navigation, a decision their own CUA standard already supported, while Microsoft (business model: 'Uber for 'my mother is not interested'') deflected with a mother joke. Hackernews, literally all of whom are experts in 3270 terminal keycaps and 1980s patent law, spent 28 comments debating whether the Tab key should be a sacred formatting character or a field mover—a distinction that will affect approximately six people who still use dialog boxes tied to mainframe emulators. The discussion ended not with a technical victory but with a reminder that the only thing less useful than corporate hierarchy is the tech community’s obsessive documentation of which key was used to move to the next box of irrelevance.
