Only partly - they're (I assume) setting their $TERM to something other
than the terminal description that comes with rxvt, e.g., "vt100" or
"xterm" - or "ansi" or "linux".

slang uses a piece of that (look at the djgpp code).  I'd clean up some of
it, but haven't (til recently) gotten the pieces to do test builds.

It's used in ncurses as part of making the behavior in
lynx_initialize_keymaps() mirror that of slang.  That in turn was designed
to replace the chunk of hardcoded assignments at the top of LYgetch_for().
