yast on rxvt TERM

It’s not really a problem … but I noticed that while running yast in an rxvt terminal, cursor keys (at least cursor down) don’t work. It’s easy to work around by changing TERM value (for example to xterm) before starting yast. However I was wondering if you could add rxvt support to yast, as you would do for some console apps (like mc). But I guess probably not(?).
