alt Hacker News> not least when capturing numbers as the numeric key pad has Enter not Tab.
And “Enter” isn’t “Return”.
I don’t know how the PC and PC software did it, but the Mac, when it got a numeric keypad, discriminated between return (on the alphanumeric keyboard) and enter (on the keypad), and software did discriminate between the two.
On the PC you can distinguish between the two of them in "raw" mode, but almost all keyboard maps flatten them both into the same key.
The only time I've seen them mapped differently is games.
