I feel like you're being deliberately rude and not reading what I said now. First off, thanks for dismissively passing me a link I need to pay $237 to read, no thanks ISO, but also I bet it doesn't say you must enable sticky keys by pressing the key 5 times.

I know this because Macs don't have this terrible shortcut enabled. You just turn sticky keys on in the Accessibility options. I also know this because the other article you posted tells the story of Gregg Vanderheiden, who wrote the first sticky keys driver in assembly and used the 5-press as a hack to signal for his driver to take over. Once the feature was officially implemented, the 5-press should no longer have been needed as a trigger.

And in fact, the "rogue developer" (Ed Tecot) who bravely worked on accessibility features from further down in the backlog for the Mac didn't implement the 5-press either. And that article specifically calls out Microsoft, by the original designer, for having a bad shortcut!

It’s turned off by default on Macs—as the inventors intended. “You want sticky keys turned off by default because it’s just going to annoy them,” shared Vanderheiden in the call. “It doesn’t help you, it doesn’t help them, it doesn’t help the disability community.” But somehow, the wires got crossed with Windows, and to this day it’s enabled by default, an accidental 5-Shift-press away from discovery.
