+### Pop-up terminals
+
+JOE 4.0 introduced pop-up virtual terminals accessible via the `F1`-`F4` keys.
+These terminals are improved over the previous type (which were invoked with
+`^K '`) in that they interpret ANSI codes and can update any part of the
+screen.  This is (partially) supported in the Windows version with the help
+of [winpty](https://github.com/rprichard/winpty) (by Ryan Prichard).
+
+By default, the standard Windows command interpreter (`cmd`) is loaded when you
+start a new virtual terminal, but this is configurable by modifying the
+`vt.bat` script.  It can be made to run Powershell or Cygwin out-of-the-box, or
+another shell with a little modification.  Powershell and `cmd` both require
+winpty (which screen-scrapes a hidden console), whereas Cygwin can be used
+more <i>directly</i> through a pseudo terminal with the help of the `socat`
+package. (`socat` does not come installed by default on Cygwin, so if you plan
+to use it you should install it.)
+
+Generally, you should copy the `vt` directory to your local user directory and
+modify `vt.bat` to choose your shell (instructions can be found at the top of
+that file).
+
+    xcopy /S /I "C:\Program Files (x86)\JoeEditor\vt" "%LOCALAPPDATA%\JoeEditor\vt"
+    joe "%LOCALAPPDATA%"\JoeEditor\vt\vt.bat
+
+There is currently a bug in winpty that does not propagate `^C` to some programs
+(most notably, the shell).  Attempts to fix this delayed a couple of releases,
+so as of now it is currently broken.  This, however, does not apply to Cygwin.
