GoKawiilFigma traces decades-old Shift+Numpad bug to IBM's 1977 keyboard design
A Figma engineer investigated a user-reported quirk where Shift+2 worked differently depending on whether it was pressed via the main keyboard or the numeric keypad, but only on Windows. The investigation traced the behavior back to keyboard layout decisions IBM made starting with its 1977 System/34 and carried forward through the Datamaster and the original IBM PC.
