Having actually used &quot;dumb terminals&quot;, like the DEC VT-100, Qume QVT-101 and others over RS-232 connections and shoe-box sized modems way back in the 80&#x27;s I found the start of your comment to be somewhat funny.<p>Not criticizing your post at all.  Simply making the observation that what we might call a &quot;dumb terminal&quot; today is a million miles away from where this term originated.  Just like the &quot;film industry&quot; is really the &quot;digital image industry&quot; today.<p>I remember running AutoCAD 1.2 on an 8086-based S-100 CP&#x2F;M system with the addition of an 8087 match co-processor card, 640K of RAM, 1 MB on a RAMDISK card, a tablet with a puck that used a magnetic coil to sense position and, yes, a DEC VT-100 &quot;dumb terminal&quot;.  Sometimes I had to unload stuff from memory just to be able to plot.  Fun times.  Funny that today developers think stuff like vim is cool.  We couldn&#x27;t wait to get off those damn terminals and use &quot;real&quot; editors.<p>Who knows what Ctrl-K-X belongs to?
