Well, that was kind of the point.<p>The original Mac OS was designed to be mouse-first. Keyboard shortcuts were there, but only to be used as well as, not instead of the mouse.<p>Windows had to be completely usable by keyboard as it began as a graphical overlay to a keyboard-only interface - and it wasn&#x27;t possible to guarantee every machine it was on had a mouse.<p>It&#x27;s a bit like now I suppose. iOS was designed to be touch-first, with limited keyboard and no pointer support, and Windows adds a touch overlay to a keyboard and pointer-first system.
