Probably not on Microsoft Windows, although I'm willing to add Windows support if someone cares enough to research a good and easy approach using current Windows facilities (not Win32 FFI calls). (Of course, you can always run the Racket code on GNU/Linux or Mac OS X, while using as your display an SSH client terminal emulator running on Windows.) If someone is programming with CharTerm and wants example code, in addition to the "demo.rkt" that comes with CharTerm, there is also Rackonsole ("<a href="http://www.neilvandyke.org/rackonsole/" target="_blank">http://www.neilvandyke.org/rackonsole/</a>"). "demo.rkt" might be a good copy&paste starting point for one's app event loop with window resizing. One can discard the code in "demo.rkt" for the editable text widget. (The editable text widget and the window-resizing event loop skeleton both might become library features in the future, but for now it's copy&paste from "demo.rkt".) Neil V.

Possibly need some library like curses in UNIX (though I now use Windows). Supposing to write a text editor like vi with Racket, how do you guys to write codes using h, j, k, and l keys as cursor? In the case with standard input and output, as you know, it is impossible to emulate the move.
