Shift Delete on Cygwin/Xemacs-21.1-p2

Hi When I do C-h k and then Control Insert or Shift Insert I get: C-insert runs `copy-primary-selection' Sh-insert runs `yank-clipboard-selection' but C-h k and then pressing Shift Delete gives me: DEL runs `scroll-down' It seems that Sh-delete is not recognized on my system. Any hint ?
