    I am enjoying this revolutionary 1968 (wrongly labeled as 1976) presentation of hyperlinks, mouse technology, multipoint conferencing, etc. by Doug Engelbart...

    but I can't help wondering about the keyboard device he is using. I recognize the keyboard itself, and the (3-button!) mouse on the right, but what is that set of 5 "keys" or control bars he is manipulating with his left hand? He sorta-kinda explains, but I don't quite get it....

    Cool + no idea about the keyboard. Thanks for the link!

    I know a little more now. Apparently it's called a "chording keyboard." The user can make various key-touch combinations to indicate any character in the alphabet, so he can enter text or commands (like modern function-key combos?) while moving the mouse pointer simultaneously....But I still don't quite grasp the details. At first I thought this device was just a relic, but I've found several companies that do make chording keyboards to this day, most commonly for Braille users. I'd just never seen one before. I guess it's also the thing stenographers use in court....

    What a demo. Videoconferencing, email, collaborative multi-point file manipulation, GUI, chart drawing.... :eek:

    So, the idea is one hand on the mouse, the other typing using the five keys? Pity they're not widely available today!
