Oh cool, TIL! I have glazed over the contents of termios(3) which may have similar roots, or atleast built ontop of similar abstractions.

now that sounds interesting. I've only seen a few screnshots of plan9 and an old video or two but not much. My friend actually has it up and running on his system.
So this editing thing. Would you hit some key to bring up a text window dialog, then enter your text, edit it and whatevs (using sam?), then send it ... anywhere, your printer, your rc, your email, a file. Or would you be in that application and have to manually copy text and then edit (ala how i use tmux actually) then edit it, then paste it back?

Yeh i can see how you could still do a lot with that.

Cheers for the enlightenment!
