MIT "space-cadet" keyboard, a pre-ISO/IEC 9995 keyboard with a large number of modifier keys. It was equipped with four keys for bucky bits (Control, Meta, Hyper, and Super); and three shift keys, called "shift", "top", and "front".

Yes indeed! Back when I was doing audio transcription it was kinda handy for some Wordperfect 5.1 functions. But no, I don't think that thing has been real useful since the Late Jurassic or so.

Could be worse, Doc. Imagine the universe where THIS became the standard... #doublebucky #youretheone
