 +Why "Modified Nasa"?  Is it in fact modified Alpha-dot((https://apps.dtic.mil/sti/citations/AD0774841))? No, but they seem to have happened around the same time.  I don't in fact know the origin of this chording system. InfoGrip used it for years on their now discontinued [[https://www.infogrip.com/bat-keyboard.html|BAT chording keyboard]], but early on I was told that NASA developed it, so I called my version "Modified Nasa". If you know more or can provide a footnote, please let me know.
